| |
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.
make dirty expire time a moving target [PATCH 1/6] writeback: pass writeback_control down to move_expired_inodes() [PATCH 2/6] writeback: the kupdate expire timestamp should be a moving target [PATCH 3/6] writeback: sync expired inodes first in background writeback
loop condition fixes (the most tricky part) [PATCH 4/6] writeback: introduce writeback_control.inodes_cleaned [PATCH 5/6] writeback: try more writeback as long as something was written
NFS fix [PATCH 6/6] NFS: return -EAGAIN when skipped commit in nfs_commit_unstable_pages()
Thanks, Fengguang
