Andrew, I'd like to propose a cleaner way of using the s_dirty, s_io, s_more_io queues for the writeback of dirty inodes. The basic idea is to clearly define the function of the queues, especially to decouple s_diry from s_io/s_more_io. The details are in the changelog of patch 2. The patches are some cleanups on top of Andrew's s_dirty time-ordering patches and Ken's s_more_io patch: [PATCH 1/4] writeback: check time-ordering of s_io and s_more_io [PATCH 2/4] writeback: 3-queue based writeback schedule [PATCH 3/4] writeback: function renames and cleanups [PATCH 4/4] writeback: fix ntfs with sb_has_dirty_inodes() fs/fs-writeback.c | 196 +++++++++++++++++++++++-------------------- fs/ntfs/super.c | 4 include/linux/fs.h | 1 3 files changed, 108 insertions(+), 93 deletions(-) Note that the patches need rework for inserting into the right place of your queue of -mm patches. I'll take care of it in the next take.
