Changes since v7: - Fold the "include default_backing_dev_info in writeback" patch into the core, we should just do it from the beginning. - More series cleanup, I think it should be mostly complete now. No hunks are split between patches now (things like comments for functions added earlier, and so on). - Fix hang with calling bdi_wait_on_work_clear() inside the bdi_lock mutex when the default wb thread had exited. - Fix hang with queuing work on exited wb thread, it would have no receipients since the default wb thread wrongly cleared the bit from the register mask on exit. It must be persistent, which is why it gets initialized on bdi_register() already. For ease of patching, I've put the full diff here: http://kernel.dk/writeback-v8.patch and also stored this in a writeback-v7 branch that will not change, you can pull that into Linus tree from here: git://git.kernel.dk/linux-2.6-block.git writeback-v8 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 | 24 - b/fs/buffer.c | 2 b/fs/char_dev.c | 1 b/fs/configfs/inode.c | 1 b/fs/fs-writeback.c | 807 +++++++++++++++++++++++++++------- b/fs/fuse/inode.c | 1 b/fs/hugetlbfs/inode.c | 1 b/fs/nfs/client.c | 1 b/fs/ntfs/super.c | 33 - 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 | 74 +++ 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 | 476 +++++++++++++++++++- b/mm/page-writeback.c | 151 ------ b/mm/swap_state.c | 1 b/mm/vmscan.c | 2 mm/pdflush.c | 269 ----------- 28 files changed, 1248 insertions(+), 637 deletions(-) -- Jens Axboe
