Hi, Here's the 15th version of the writeback patches. Changes since v14: - Collapsed a few patches and got rid of the multiple thread support. The work items remain, it's been well tested and means that you can queue work for a bdi without blocking and waiting for it to finish the existing work. Lazy exit is now included in the first patch. - I kept the 'remove pdflush' patch separate. The main patch is already big enough, and thinking about it, I think it makes sense to retain as a separate patch. Christoph, let me know if there are things you are still not happy with and I will reply/address them. Note that this series has only received a light testing. This means that it boots and seems to work (flushes data on sync and at intervals) and does not corrupt data, but it hasn't received a thorough testing yet. That will come tomorrow. But I wanted to push this out there, so we can settle the code base quickly again. 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 | 907 ++++++++++++++++++++++++---------- 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/sync.c | 2 b/fs/sysfs/inode.c | 1 b/fs/ubifs/super.c | 1 b/include/linux/backing-dev.h | 57 ++ b/include/linux/fs.h | 10 b/include/linux/writeback.h | 19 b/kernel/cgroup.c | 1 b/kernel/sysctl.c | 8 b/mm/Makefile | 2 b/mm/backing-dev.c | 379 +++++++++++++- b/mm/page-writeback.c | 165 +----- b/mm/swap_state.c | 1 b/mm/vmscan.c | 2 mm/pdflush.c | 269 ---------- 28 files changed, 1145 insertions(+), 695 deletions(-) -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
