This is just a rebase to linus' latest master. I haven't heard any feedback on this one so Jan suggested I send to a wider audience. Brian v8: - Rebased to latest master. - Added Holger's Tested-by. v7: http://marc.info/?l=linux-fsdevel&m=145349651407631&w=2 - Updated patch 1/2 commit log description to reference performance impact. v6: http://marc.info/?l=linux-fsdevel&m=145322635828644&w=2 - Use rcu locking instead of s_inode_list_lock spinlock in wait_sb_inodes(). - Refactor wait_sb_inodes() to keep inode on wb list. - Drop remaining, unnecessary lazy list removal bits and relocate inode list check to clear_inode(). - Fix up some comments, etc. v5: http://marc.info/?l=linux-fsdevel&m=145262374402798&w=2 - Converted from per-bdi list to per-sb list. Also marked as RFC and dropped testing/review tags. - Updated to use new irq-safe lock for wb list. - Dropped lazy list removal. Inodes are removed when the mapping is cleared of the writeback tag. - Tweaked wait_sb_inodes() to remove deferred iput(), other cleanups. - Added wb list tracepoint patch. v4: http://marc.info/?l=linux-fsdevel&m=143511628828000&w=2 Brian Foster (1): wb: inode writeback list tracking tracepoints Dave Chinner (1): sb: add a new writeback list for sync fs/fs-writeback.c | 111 ++++++++++++++++++++++++++++++--------- fs/inode.c | 2 + fs/super.c | 2 + include/linux/fs.h | 4 ++ include/linux/writeback.h | 3 ++ include/trace/events/writeback.h | 22 ++++++-- mm/page-writeback.c | 18 +++++++ 7 files changed, 133 insertions(+), 29 deletions(-) -- 2.5.5 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
