From 5bc970e803ad2b1f26771f39376a79dbf0f5bf64 Mon Sep 17 00:00:00 2001 From: Sunil Mushran Date: Tue, 28 Dec 2010 23:26:03 -0800 Subject: ocfs2: Use hrtimer to track ocfs2 fs lock stats Patch makes use of the hrtimer to track times in ocfs2 lock stats. The patch is a bit involved to ensure no additional impact on the memory footprint. The size of ocfs2_inode_cache remains 1280 bytes on 32-bit systems. A related change was to modify the unit of the max wait time from nanosec to microsec allowing us to track max time larger than 4 secs. This change necessitated the bumping of the output version in the debugfs file, locking_state, from 2 to 3.

But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. This patch just try to remove it or change it. So: 1. if all the error paths already use mlog_errno, it is just removed. Otherwise, it will be replaced by mlog_errno. 2. if it is used to print some return value, it is replaced with mlog(0,...). mlog_exit_ptr is changed to mlog(0. All those mlog(0,...) will be replaced with trace events later.

Wengang has did some work in his original patch http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005513.html But he didn't finished it. So this patch removes all mlog(0,...) from alloc.c and adds the corresponding trace events. Different mlogs have different solutions. 1. Some are replaced with trace event directly. 2. Some are replaced and some new parameters are added since I think we need to know the btree owner in that case. 3. Some are combined into one trace events. 4. Some redundant mlogs are removed. What's more, it defines some event classes so that we can use them later.

So this patch removes all mlog(0,...) from localalloc.c and adds the corresponding tracepoints. Different mlogs have different solutions. 1. Some are replaced with trace event directly. 2. Some are replaced while some new parameters are added. 3. Some are combined into one trace events. 4. Some redundant mlogs are removed.

These IP cores are included in many multifunction devices, in sh-mobile chips from Renesas, in the latter case they can also use DMA. Some sh-mobile implementations also have some other specialities, that MFD-based solutions don't have. This makes supporting all these features in a monolithic driver inconveniet and error-prone. This patch splits the driver into 3 parts: the core, the MFD glue and the DMA support. In case of a modular build, two modules will be built: mmc_tmio_core and mmc_tmio.

To avoid this deadlock, separate the inode cluster buffer locking semantics from the synchronous inode flush semantics, allowing callers to attempt to lock the buffer but still issue synchronous IO if it can get the buffer. This requires xfs_iflush() calls that currently use non-blocking semantics to pass SYNC_TRYLOCK rather than 0 as the flags parameter. This allows xfs_reclaim_inode to avoid the deadlock on the buffer lock and detect the failure so that it can drop the inode ilock and restart the reclaim attempt on the inode. This allows xfs_ifree_cluster to obtain the inode lock, mark the inode stale and release it and hence defuse the deadlock situation. It also has the pleasant side effect of avoiding IO in xfs_reclaim_inode when it tries to next reclaim the inode as it is now marked stale.

If there are more inodes in the filesystem than can be held in memory, we require the inode cache shrinker to run to ensure that we don't run out of memory. Unfortunately, the inode cache shrinker is not registered until we get to the end of the superblock setup process, which is after a quotacheck is run if it is needed. Hence we need to register the inode cache shrinker earlier in the mount process so that we don't OOM during mount. This requires that we also initialise the syncd work before we register the shrinker, so we nee dto juggle that around as well. While there, make sure that we have set up the block sizes in the VFS superblock correctly before the quotacheck is run so that any inodes that are cached as a result of the quotacheck have their block size fields set up correctly.

Convert the buffer cache to use alloc_pages() instead of the page cache. This will remove all the overhead of page cache management from setup and teardown of the buffers, as well as needing to mark pages accessed as we find buffers in the buffer cache. By avoiding the page cache, we also remove the need to keep state in the page_private(page) field for persistant storage across buffer free/buffer rebuild and so all that code can be removed. This also fixes the long-standing problem of not having enough bits in the page_private field to track all the state needed for a 512 sector/64k page setup. It also removes the need for page locking during reads as the pages are unique to the buffer and nobody else will be attempting to access them. Finally, it removes the buftarg address space lock as a point of global contention on workloads that allocate and free buffers quickly such as when creating or removing large numbers of inodes in parallel. This remove the 16TB limit on filesystem size on 32 bit machines as the page index (32 bit) is no longer used for lookups of metadata buffers - the buffer cache is now solely indexed by disk address which is stored in a 64 bit field in the buffer.

Currently we either want to refill a cluster with 1) All normal extent entries (those without bitmaps) 2) A bitmap entry with enough space The current code has this ugly jump around logic that will first try and fill up the cluster with extent entries and then if it can't do that it will try and find a bitmap to use. So instead split this out into two functions, one that tries to find only normal entries, and one that tries to find bitmaps. This also fixes a suboptimal thing we would do with bitmaps. If we used a bitmap we would just tell the cluster that we were pointing at a bitmap and it would do the tree search in the block group for that entry every time we tried to make an allocation. Instead of doing that now we just add it to the clusters group. I tested this with my ENOSPC tests and xfstests and it survived.

The regulator core had suspend-prepare that turns off the regulators when entering a system-wide suspend. However, it did not have suspend-finish that pairs with suspend-prepare and the regulator core has assumed that the regulator devices and their drivers support autonomous recover at resume. This patch adds regulator_suspend_finish that pairs with the previously-existed regulator_suspend_prepare. The function regulator_suspend_finish turns on the regulators that have always_on set or positive use_count so that we can reset the regulator states appropriately at resume. In regulator_suspend_finish, if has_full_constraints, it disables unnecessary regulators.

As far as i understand it, it should behave like when originating packets. Currently it will only timestamp the next free slot if: - there is space for *two* timestamps - some random data from the echoed packet taken as an IP is *not* a local IP This first is caused by an off-by-one error. 'soffset' points to the next free slot and so we only need to have 'soffset + 7 <= optlen'. The second bug is using sptr as the start of the option, when it really is set to 'skb_network_header(skb)'. I just use dptr instead which points to the timestamp option. Finally it would only timestamp for non-local IPs, which we shouldn't do. So instead we exclude all unicast destinations, similar to what we do in ip_options_compile().

I suspect that growing the encrypted file was to prevent an information leak that the unencrypted file was empty. However, the unencrypted file size is stored, in plaintext, in the metadata so growing the file is unnecessary.

This has been proposed previously, but VFS developers wanted us to use generic ioctls rather than btrfs-specific ones. According to Chris's comment, there should be just one true compression method(probably LZO) stored in the super. However, before this, we would wait for that one method is stable enough to be adopted into the super. So I list it as a long term goal, and just store it in ram today. After applying this patch, we can use the generic "FS_IOC_SETFLAGS" ioctl to control file and directory's datacow and compression attribute. NOTE: - The compression type is selected by such rules: If we mount btrfs with compress options, ie, zlib/lzo, the type is it. Otherwise, we'll use the default compress type (zlib today). v1->v2: - rebase to the latest btrfs. v2->v3: - fix a problem, i.e. when a file is set NOCOW via mount option, then this NOCOW will be screwed by inheritance from parent directory.

However, in this case I believe EXDEV to be the more appropriate value. >From the link(2) man page: EXDEV oldpath and newpath are not on the same mounted file system. (Linux permits a file system to be mounted at multiple points, but link() does not work across different mount points, even if the same file system is mounted on both.) This matters because an application may have different behaviors based on return codes.

When wireless hotpluging is enabled, toggling the status of the wireless device using WMBC will trigger a notification and the notification handler need to call WMBC again to get the new status of the device, this will trigger the following error: ACPI Error (dswload-0802): [_T_0] Namespace lookup failure, AE_ALREADY_EXISTS ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20100428/psloop-231) ACPI Error (psparse-0537): Method parse/execution failed [\AMW0.WMBC] (Node f7023b88), AE_ALREADY_EXISTS ACPI: Marking method WMBC as Serialized because of AE_ALREADY_EXISTS error Since there is currently no way to tell the acpi subsystem to mark a method as serialized, we do it in eeepc-wmi. Of course, we could let the first call fail, and then it would work, but it doesn't seems really clean, and it will make the first WMBC call return a random value. This patch was tested on EeePc 1000H with a RaLink RT2860 wireless card using the rt2800pci driver. rt2860sta driver seems to deadlock when we remove the pci device...

Removing them allow to remove a lot of code an significantly clean the driver. This will affect the backlight code which won't be able to know if the backlight is on or off.

Since we don't want to load eeepc-wmi module on Asus notebooks, and we want to keep the eeepc-wmi module for backward compatibility, this patch introduce a new module, named asus-wmi, that will be used by eeepc-wmi and the new Asus Notebook WMI Driver. eeepc-wmi's input device strings (device name and phys) are kept, but rfkill and led names are changed (s/eeepc/asus/). This should not break anything since rfkill are used by type or index, not by name, and the eeepc::touchpad led wasn't working correctly before 2.6.39 anyway.

But there is no way to know if there is an Eee PC in that wild that is using 0x53545344 or a notebook using 0x53544344. So the driver try to guess the available DSTS method ... But most Eee PCs never return 0xFFFFFFFE when a method is not available, they return 0 instead (and that's useless). So, first, try 0x53544344 then 0x53545344. We will find a better way when we got more data.

However, it used the horrible old functions names from , that were never really meant to be exported. In the meantime, things got cleaned up, and in commit c4945b9ed472 ("asm-generic: rename generic little-endian bitops functions") we renamed the LE bitops to something sane, exactly so that they could be used in random code without people gouging their eyes out when seeing the crazy jumble of letters that were the old internal names. As a result the drbd thing merged cleanly (commit 8d49a77568d1: "Merge branch 'for-2.6.39/drivers' of git://git.kernel.dk/linux-2.6-block"), since there was no data conflict - but the end result obviously doesn't actually compile.

The subtle differences are 1) The handler checks for IRQ_DISABLED after the device handler has been called. In case it's set it masks the interrupt. 2) When the handler sees IRQ_DISABLED on entry it masks the interupt in the same way as handle_fastoei_irq, but does not set the IRQ_PENDING flag. 3) Instead of gracefully handling a recursive interrupt it crashes the kernel. #1 is just relevant when a device handler calls disable_irq_nosync() and it does not matter whether we mask the interrupt right away or not. We handle lazy masking for disable_irq anyway, so there is no real reason to have this extra mask in place. #2 will prevent the resend of a pending interrupt, which can result in lost interrupts for edge type interrupts. For level type interrupts the resend is a noop in the generic code. According to the datasheet all interrupts are level type, so marking them as such will result in the exact same behaviour as the private handle_prio_irq implementation. #3 is just stupid. Crashing the kernel instead of handling a problem gracefully is just wrong. With the current semantics- all handlers run with interrupts disabled - this is even more wrong. Rename ack to eoi, remove the unused mask_ack, switch to handle_fasteoi_irq and remove the private function.

There are several legitimate places where glibc wants to queue a negative si_code different from SI_QUEUE: - This was first noticed with glibc's aio implementation, which wants to queue a signal with si_code SI_ASYNCIO; the current kernel causes glibc's tst-aio4 test to fail because rt_sigqueueinfo() fails with EPERM. - Further examination of the glibc source shows that getaddrinfo_a() wants to use SI_ASYNCNL (which the kernel does not even define). The timer_create() fallback code wants to queue signals with SI_TIMER. As suggested by Oleg Nesterov , loosen the check to forbid only the problematic SI_TKILL case.

We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

That removes the extra status check in the callback. 2) Use the preflow handler, which is called from the fasteoi core code before the device handler. That avoids another status check and the open coded handler redirection.
