..."write: in ..." and "fsync: out ...". The problem was occurred since 2.6.5-bk1, which includes the patch "[PATCH] ext3 fsync() and fdatasync() speedup". We found that the problem was solved by deleting the part of the patch which modifies ext3_sync_file(). Maybe, i_state is not correctly set to I_DIRTY when the related page cache is dirty (is it true?) Attached file is tarball (tar + bzip2) which contains following files. The patches are for 2.6.8.1-kernel (applicable to 2.6.9-rc2), and the results were also produced with 2.6.8.1-kernel. - fsync.c.patch: patch f...

Hi. In ocfs2, fdatasync and fsync are identical. I think fdatasync should skip committing transaction when inode->i_state is set just I_DIRTY_SYNC and this indicates only atime or/and mtime updates. Following patch improves fdatasync throughput. #sysbench --num-threads=16 --max-requests=300000 --test=fileio --file-block-size=4K --file-total-size=16G --file-test-mode=rndwr --file-fsync-mode=fdatasync run Results: -...

...2(t0) fffffc0000883f78: 08 a1 7d a7 ldq t12,-24312(gp) [...] The ldl_l .... stl_c sequence can be identified as test_and_clear_bit() on alpha. So the faulting instruction is this line of fs/ext3/inode.c::ext3_bmap() : if (test_and_clear_bit(EXT3_STATE_JDATA, &inode->u.ext3_i.i_state)) In fact ext3_i.i_state is a 16 bit aligned 16 bit value while test_and_clear_bit() expects to work on aligned 32 bit quantities. Furthermore the unaligned trap handler doesn't know how to handle the ldl_l. How to fix it? Weird side note: ext3 0.0.7 on kernel 2.4.5-ac22 worked without prob...

This happens on a freshly created btrfs filesystem in a raid10 (4x1TB) configuration with three subvolumes and 1.5 TB data. When I try to snapshot one of the subvolumes (with 100 GB of data), it says that the snapshot creation failed and I get the following error message: btrfs: could not do orphan cleanup -116 After the failure: - The snapshot exists in `btrfs subvolume list'' - The

All, Please review the patches backported to 1.4 from mainline. Sunil

i_alloc_sem has always been a bit of an odd "lock". It''s the only remaining rw_semaphore that can be released by a different thread than the one that locked it, and it''s use case in the core direct I/O code is more like a counter given that the writers already have external serialization. This series removes it in favour of a simpler counter scheme, thus getting rid
