2008-12-31anon_inodes: use fops->owner for module refcountChristian Borntraeger
There is an imbalance for anonymous inodes. If the fops->owner field is set, the module reference count of owner is decreases on release. ("filp_close" --> "__fput" ---> "fops_put") On the other hand, anon_inode_getfd does not increase the module reference count of owner. This causes two problems: - if owner is set, the module refcount goes negative - if owner is not set, the module can be unloaded while code is running This patch changes anon_inode_getfd to be symmetric regarding fops->owner handling. I have checked all existing users of anon_inode_getfd. Noone sets fops->owner, thats why nobody has seen the module refcount negative. The refcounting was tested with a patched and unpatched KVM module.(see patch 2/2) I also did an epoll_open/close test.

2008-12-31UBIFS: fix writing uncompressed filesArtem Bityutskiy
UBIFS does not disable compression if ui->flags is non-zero, e.g. if the file has "sync" flag. This is because of the typo which is fixed by this patch. The patch also adds a couple of useful debugging prints. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

These are mostly long lines and wrong indentation warning fixes.

2008-12-31UBIFS: simplify make_free_spaceArtem Bityutskiy

2008-12-31UBIFS: do not lie about used blocksArtem Bityutskiy
Do not force UBIFS return 0 used space when it is empty. It leads to a situation when creating any file immediately produces tens of used blocks, which looks very weird. It is better to be honest and say that some blocks are used even if the FS is empty. And ext2 does the same. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: restore budg_uncommitted_idxArtem Bityutskiy
UBIFS stores uncommitted index size in c->budg_uncommitted_idx, and this affect budgeting calculations. When mounting and replaying, this variable is not updated, so we may end up with "over-budgeting". This patch fixes the issue. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: always commit on unmountArtem Bityutskiy
UBIFS commits on unmount to make the next mount faster. Currently, it commits only if there is more than LEB size bytes in the journal. This is not very good, because journal size may be large (512KiB). And there may be few deletions in the journal which do not take much journal space, but which do introduce a lot of TNC changes and make mount slow. Thus, jurt remove this condition and always commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-12-31UBIFS: always commit in sync_fsArtem Bityutskiy
Always run commit in sync_fs, because even if the journal seems to be almost empty, there may be a deletion which removes a large file, which affects the index greatly. And because we want better free space predictions after 'sync_fs()', we have to commit. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2008-12-31UBIFS: fix file-system synchronizationArtem Bityutskiy
Argh. The ->sync_fs call is called _before_ all inodes are flushed. This means we first sync write buffers and commit, then all inodes are synced, and we end up with unflushed write buffers! Fix this by forcing synching all indoes from 'ubifs_sync_fs()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

2008-12-29bio: get rid of bio_vec clearingJens Axboe
We don't need to clear the memory used for adding bio_vec entries, since nobody should be looking at members unitialized.

2008-12-29Get rid of CONFIG_LSFJens Axboe

2008-12-29aio: make the lookup_ioctx() locklessJens Axboe
The mm->ioctx_list is currently protected by a reader-writer lock, so we always grab that lock on the read side for doing ioctx lookups. As the workload is extremely reader biased, turn this into an rcu hlist so we can make lookup_ioctx() lockless. Get rid of the rwlock and use a spinlock for providing update side exclusion. There's usually only 1 entry on this list, so it doesn't make sense to look into fancier data structures. Reviewed-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-12-29bio: add support for inlining a number of bio_vecs inside the bioJens Axboe
When we go and allocate a bio for IO, we actually do two allocations. One for the bio itself, and one for the bi_io_vec that holds the actual pages we are interested in. This feature inlines a definable amount of io vecs inside the bio itself, so we eliminate the bio_vec array allocation for IO's up to a certain size. It defaults to 4 vecs, which is typically 16k of IO. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-12-29bio: allow individual slabs in the bio_setJens Axboe
Instead of having a global bio slab cache, add a reference to one in each bio_set that is created. This allows for personalized slabs in each bio_set, so that they can have bios of different sizes. This means we can personalize the bios we return. File systems may want to embed the bio inside another structure, to avoid allocation more items (and stuffing them in ->bi_private) after the get a bio. Or we may want to embed a number of bio_vecs directly at the end of a bio, to avoid doing two allocations to return a bio. This is now possible. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2008-12-29bio: only mempool back the largest bio_vec slab cacheJens Axboe
We only very rarely need the mempool backing, so it makes sense to get rid of all but one of the mempool in a bio_set. So keep the largest bio_vec count mempool so we can always honor the largest allocation, and "upgrade" callers that fail. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-12-29block: Supress Buffer I/O errors when SCSI REQ_QUIET flag setKeith Mannthey
Allow the scsi request REQ_QUIET flag to be propagated to the buffer file system layer. The basic ideas is to pass the flag from the scsi request to the bio (block IO) and then to the buffer layer. The buffer layer can then suppress needless printks. This patch declutters the kernel log by removed the 40-50 (per lun) buffer io error messages seen during a boot in my multipath setup . It is a good chance any real errors will be missed in the "noise" it the logs without this patch. During boot I see blocks of messages like " __ratelimit: 211 callbacks suppressed Buffer I/O error on device sdm, logical block 5242879 Buffer I/O error on device sdm, logical block 5242879 Buffer I/O error on device sdm, logical block 5242847 Buffer I/O error on device sdm, logical block 1 Buffer I/O error on device sdm, logical block 5242878 Buffer I/O error on device sdm, logical block 5242879 Buffer I/O error on device sdm, logical block 5242879 Buffer I/O error on device sdm, logical block 5242879 Buffer I/O error on device sdm, logical block 5242879 Buffer I/O error on device sdm, logical block 5242872 " in my logs. My disk environment is multipath fiber channel using the SCSI_DH_RDAC code and multipathd. This topology includes an "active" and "ghost" path for each lun. IO's to the "ghost" path will never complete and the SCSI layer, via the scsi device handler rdac code, quick returns the IOs to theses paths and sets the REQ_QUIET scsi flag to suppress the scsi layer messages. I am wanting to extend the QUIET behavior to include the buffer file system layer to deal with these errors as well. I have been running this patch for a while now on several boxes without issue. A few runs of bonnie++ show no noticeable difference in performance in my setup. Thanks for John Stultz for the quiet_error finalization.

2008-12-26proc: remove ifdef CONFIG_SPARSE_IRQ from stat.cKOSAKI Motohiro
Impact: cleanup irq_desc can be NULL when CONFIG_SPARSE_IRQ=y only. therefore, NULL checking can move into kstat_irqs_cpu() of SPARSE_IRQ version. Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Acked-by: "Yinghai Lu" <yinghai@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-12-26[CIFS] Remove redundant testJulia Lawall
In fs/cifs/cifssmb.c, pLockData is tested for being NULL at the beginning of the function, and not reassigned subsequently. A simplified version of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Steve French <sfrench@us.ibm.com>
2008-12-26[CIFS] make sure that DFS pathnames are properly formedSteve French
The paths in a DFS request are supposed to only have a single preceding backslash, but we are sending them with a double backslash. This is exposing a bug in Windows where it also sends a path in the response that has a double backslash. The existing code that builds the mount option string however expects a double backslash prefix in a couple of places when it tries to use the path returned by build_path_from_dentry. Fix compose_mount_options to expect properly formed DFS paths (single backslash at front). Also clean up error handling in that function. There was a possible NULL pointer dereference and situations where a partially built option string would be returned. Tested against Samba 3.0.28-ish server and Samba 3.3 and Win2k8.
