Subject: [PATCH 0/6] writeback: moving expire targets for background/kupdate works v2
Date: Wed, 20 Apr 2011 16:03:36 +0800 [thread overview]
Message-ID: <20110420080336.441157866@intel.com> (raw)
Andrew,
This aims to reduce possible pageout() calls by making the flusher
concentrate a bit more on old/expired dirty inodes.
Rationals and benchmark numbers are added in patches 05, 06.
It runs fine on simple workloads over ext3/4, xfs, btrfs and NFS.
code refactor
[PATCH 1/6] writeback: pass writeback_control down to move_expired_inodes()
loop condition fixes
[PATCH 2/6] writeback: introduce writeback_control.inodes_cleaned
[PATCH 3/6] writeback: try more writeback as long as something was written
make dirty expire time a moving target
[PATCH 4/6] writeback: the kupdate expire timestamp should be a moving target
[PATCH 5/6] writeback: sync expired inodes first in background writeback
consistent requeue policy
it's not an integral part of this patchset, however do depends on patch 03
[PATCH 6/6] writeback: refill b_io iff empty
Thanks,
Fengguang
