2008-04-28ext3: retry block allocation if new blocks are allocated from system zoneAneesh Kumar K.V
If the block allocator gets blocks out of system zone ext3 calls ext3_error. But if the file system is mounted with errors=continue retry block allocation. We need to mark the system zone blocks as in use to make sure retry don't pick them again System zone is the block range mapping block bitmap, inode bitmap and inode table.

2007-11-13Revert "ext2/ext3/ext4: add block bitmap validation"Linus Torvalds
This reverts commit 7c9e69faa28027913ee059c285a5ea8382e24b5d, fixing up conflicts in fs/ext4/balloc.c manually. The cost of doing the bitmap validation on each lookup - even when the bitmap is cached - is absolutely prohibitive. We could, and probably should, do it only when adding the bitmap to the buffer cache. However, right now we are better off just reverting it. Peter Zijlstra measured the cost of this extra validation as a 85% decrease in cached iozone, and while I had a patch that took it down to just 17% by not being _quite_ so stupid in the validation, it was still a big slowdown that could have been avoided by just doing it right.

2007-10-17lib: percpu_counter_subPeter Zijlstra
Hugh spotted that some code does: percpu_counter_add(&counter, -unsignedlong) which, when the amount argument is of type s32, sort-of works thanks to two's-complement. However when we'd change the type to s64 this breaks on 32bit machines, because the promotion rules zero extend the unsigned number. Provide percpu_counter_sub() to hide the s64 cast. That is: percpu_counter_sub(&counter, foo) is equal to: percpu_counter_add(&counter, -(s64)foo); Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Hugh Dickins <hugh@veritas.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2006-08-27[PATCH] ext3 filesystem bogus ENOSPC with reservation fixMingming Cao
To handle the earlier bogus ENOSPC error caused by filesystem full of block reservation, current code falls back to non block reservation, starts to allocate block(s) from the goal allocation block group as if there is no block reservation. Current code needs to re-load the corresponding block group descriptor for the initial goal block group in this case. The patch fixes this.

2006-06-25[PATCH] ext3_fsblk_t: filesystem, group blocks and bug fixesMingming Cao
Some of the in-kernel ext3 block variable type are treated as signed 4 bytes int type, thus limited ext3 filesystem to 8TB (4kblock size based). While trying to fix them, it seems quite confusing in the ext3 code where some blocks are filesystem-wide blocks, some are group relative offsets that need to be signed value (as -1 has special meaning). So it seem saner to define two types of physical blocks: one is filesystem wide blocks, another is group-relative blocks. The following patches clarify these two types of blocks in the ext3 code, and fix the type bugs which limit current 32 bit ext3 filesystem limit to 8TB. With this series of patches and the percpu counter data type changes in the mm tree, we are able to extend exts filesystem limit to 16TB. This work is also a pre-request for the recent >32 bit ext3 work, and makes the kernel to able to address 48 bit ext3 block a lot easier: Simply redefine ext3_fsblk_t from unsigned long to sector_t and redefine the format string for ext3 filesystem block corresponding. Two RFC with a series patches have been posted to ext2-devel list and have been reviewed and discussed: http://marc.theaimsgroup.com/?l=ext2-devel&m=114722190816690&w=2 http://marc.theaimsgroup.com/?l=ext2-devel&m=114784919525942&w=2 Patches are tested on both 32 bit machine and 64 bit machine, <8TB ext3 and >8TB ext3 filesystem(with the latest to be released e2fsprogs-1.39). Tests includes overnight fsx, tiobench, dbench and fsstress. This patch: Defines ext3_fsblk_t and ext3_grpblk_t, and the printk format string for filesystem wide blocks. This patch classifies all block group relative blocks, and ext3_fsblk_t blocks occurs in the same function where used to be confusing before. Also include kernel bug fixes for filesystem wide in-kernel block variables. There are some fileystem wide blocks are treated as int/unsigned int type in the kernel currently, especially in ext3 block allocation and reservation code. This patch fixed those bugs by converting those variables to ext3_fsblk_t(unsigned long) type.

2006-03-26[PATCH] ext3_get_blocks: Adjust reservation window size for mblocksMingming Cao
Optimize the block reservation and the multiple block allocation: with the knowledge of the total number of blocks ahead, set or adjust the reservation window size properly (based on the number of blocks needed) before block allocation happens: if there isn't any reservation yet, make sure the reservation window equals to or greater than the number of blocks needed, before create an reservation window; if a reservation window is already exists, try to extends the window size to match the number of blocks to allocate. This could increase the possibility of completing multiple blocks allocation in a single request, as blocks are only allocated in the range of the inode's reservation window.

I noticed some problems while running ext3 with the debug flag set on. More precisely, I was unable to umount the filesystem. Some investigation took me to the patch that follows. At a first glance , the lock/unlock I've taken out seems really not necessary, as the main code (outside debug) does not lock the super.

2005-06-29[PATCH] ext3: reduce allocate-with-reservation lock latenciesMingming Cao
Currently in ext3 block reservation code, the global filesystem reservation tree lock (rsv_block) is hold during the process of searching for a space to make a new reservation window, including while scaning the block bitmap to verify if the avalible window has a free block. Holding the lock during bitmap scan is unnecessary and could possibly cause scalability issue and latency issues. This patch tries to address this by dropping the lock before scan the bitmap. Before that we need to reserve the open window in case someone else is targetting at the same window. Question was should we reserve the whole free reservable space or just the window size we need. Reserve the whole free reservable space will possibly force other threads which intended to do block allocation nearby move to another block group(cause bad layout). In this patch, we just reserve the desired size before drop the lock and scan the block bitmap. This patch fixed a ext3 reservation latency issue seen on a cvs check out test. Patch is tested with many fsx, tiobench, dbench and untar a kernel test.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
