Changes since v10: - I think this finally fixes the one show stopper issue I was aware of. This is the one that Yanmin Zhang reported and which has plagued this patch series for some time. Basically it was due to a race between work queueing and exited tasks. I cleaned up this part while fixing the bug. - The three prep patches are now merged, so they have been deleted. - Updated to current -git. For ease of patching, I've put the full diff here: http://kernel.dk/writeback-v11.patch and also stored this in a writeback-v11 branch that will not change, you can pull that into Linus tree from here: git://git.kernel.dk/linux-2.6-block.git writeback-v11 Please test and report results/interesting finds. Thanks! I hope to merge this work sooner rather than later, so please do give it a good beating. b/block/blk-core.c | 1 b/drivers/block/aoe/aoeblk.c | 1 b/drivers/char/mem.c | 1 b/fs/btrfs/disk-io.c | 1 b/fs/buffer.c | 2 b/fs/char_dev.c | 1 b/fs/configfs/inode.c | 1 b/fs/fs-writeback.c | 812 +++++++++++++++++++++++++++------- b/fs/fuse/inode.c | 1 b/fs/hugetlbfs/inode.c | 1 b/fs/nfs/client.c | 1 b/fs/ocfs2/dlm/dlmfs.c | 1 b/fs/ramfs/inode.c | 1 b/fs/super.c | 3 b/fs/sysfs/inode.c | 1 b/fs/ubifs/super.c | 1 b/include/linux/backing-dev.h | 72 ++- b/include/linux/fs.h | 11 b/include/linux/writeback.h | 15 b/kernel/cgroup.c | 1 b/mm/Makefile | 2 b/mm/backing-dev.c | 530 +++++++++++++++++++++- b/mm/page-writeback.c | 157 ------ b/mm/swap_state.c | 1 b/mm/vmscan.c | 2 mm/pdflush.c | 269 ----------- 26 files changed, 1293 insertions(+), 597 deletions(-) -- Jens Axboe
