Subject: [PATCH 00/17] writeback fixes and cleanups for 2.6.40 (v2)
Date: Thu, 12 May 2011 21:57:06 +0800 [thread overview]
Message-ID: <20110512135706.937596128@intel.com> (raw)
Andrew,
This is the combination of all the recent writeback patches that get
reasonably reviewed and tested.
The first 10 patches are already in -mm tree, with updates:
- remove "writeback: pass writeback_control down to move_expired_inodes()", and
resolve the resulting merge conflicts in other patches.
- move ahead the sync livelock prevention patches (01, 02) so that (04) won't livelock sync
- merge the three -mm fixes to (08)
- fixed changelog of (01)
[PATCH 01/17] writeback: introduce .tagged_sync for the WB_SYNC_NONE sync stage
[PATCH 02/17] writeback: update dirtied_when for synced inode to prevent livelock
[PATCH 03/17] writeback: introduce writeback_control.inodes_cleaned
[PATCH 04/17] writeback: try more writeback as long as something was written
[PATCH 05/17] writeback: the kupdate expire timestamp should be a moving target
[PATCH 06/17] writeback: sync expired inodes first in background writeback
[PATCH 07/17] writeback: refill b_io iff empty
[PATCH 08/17] writeback: split inode_wb_list_lock into bdi_writeback.list_lock
[PATCH 09/17] writeback: elevate queue_io() into wb_writeback()
[PATCH 10/17] writeback: avoid extra sync work at enqueue time
The following 7 patches were posted and reviewed these days:
[PATCH 11/17] writeback: add bdi_dirty_limit() kernel-doc
[PATCH 12/17] writeback: skip balance_dirty_pages() for in-memory fs
[PATCH 13/17] writeback: remove writeback_control.more_io
[PATCH 14/17] writeback: make writeback_control.nr_to_write straight
[PATCH 15/17] writeback: remove .nonblocking and .encountered_congestion
[PATCH 16/17] writeback: trace event writeback_single_inode
[PATCH 17/17] writeback: trace event writeback_queue_io
Thanks to Jan and Dave for the careful reviews!
The patches are git pullable from
git://git.kernel.org/pub/scm/linux/kernel/git/wfg/writeback.git fs-writeback
Thanks,
Fengguang
