Andrew,
The following patches fix the sluggish writeback behavior.
They are well understood and well tested - but not yet widely tested.
The first patch reverts the debugging -mm only check_dirty_inode_list.patch -
which is no longer necessary.
The following 4 patches do the real jobs:
[PATCH 2/5] writeback: fix time ordering of the per superblock inode lists 8
[PATCH 3/5] writeback: fix ntfs with sb_has_dirty_inodes()
[PATCH 4/5] writeback: remove pages_skipped accounting in __block_write_full_page()
[PATCH 5/5] writeback: introduce writeback_control.more_io to indicate more io
They share the same goal as the following patches in -mm. Therefore I'd
recommend to put the last 4 new ones after them:
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists.patch
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists-2.patch
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists-3.patch
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists-4.patch
writeback-fix-comment-use-helper-function.patch
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists-5.patch
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists-6.patch
writeback-fix-time-ordering-of-the-per-superblock-dirty-inode-lists-7.patch
writeback-fix-periodic-superblock-dirty-inode-flushing.patch

Hi Fenguang,
now that Peters stuff seems to make it into mainline, do you think
your fixes should go in as well? Would definitely help to broaden the
tester base. Definitely by one very interested tester :-)
Keep on the good work
Martin
