Changes since last time: - Rearranged the obvious and prep patches to be at the beginning of the series. That's patches 1-3, they will go upstream for 2.6.30 since they are just cleanups. - The other change is more interesting. It adds support for > 1 flusher thread per bdi. Comments welcome, I'm particularly curious whether the super_operation is the right place to add this or not. We'll also need a few other changes, particularly I think that users of this will want to provide their own generic_sync_wb_inodes() at least. Probably along with their own variants of queue_io/requeue_io/redirty_tail() and so on. - Various little bug fixes. 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 | 3 b/fs/buffer.c | 2 b/fs/char_dev.c | 1 b/fs/configfs/inode.c | 1 b/fs/fs-writeback.c | 490 +++++++++++++++++++++++----------- b/fs/fuse/inode.c | 1 b/fs/hugetlbfs/inode.c | 1 b/fs/nfs/client.c | 1 b/fs/ntfs/super.c | 32 -- b/fs/ocfs2/dlm/dlmfs.c | 1 b/fs/ramfs/inode.c | 1 b/fs/super.c | 14 b/fs/sync.c | 16 - b/fs/sysfs/inode.c | 1 b/fs/ubifs/super.c | 1 b/include/linux/backing-dev.h | 62 ++++ 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 | 429 +++++++++++++++++++++++++++++ b/mm/page-writeback.c | 140 --------- mm/pdflush.c | 251 ----------------- b/mm/readahead.c | 25 - b/mm/swap_state.c | 1 b/mm/vmscan.c | 2 29 files changed, 889 insertions(+), 619 deletions(-) -- Jens Axboe
