Cover letter [PATCH 0/6] writeback: moving expire targets for background/kupdate works
Andrew,
This aims to reduce possible pageout() calls by making the flusher concentrate a bit more on old/expired dirty inodes.
Patches 04, 05 have been updated since last post, please review. The concerns from last review have been addressed.
It runs fine on simple workloads over ext3/4, xfs, btrfs and NFS.
Trond, will you take the last patch? The fixed "bug" has no real impact for now.
