Subject: [PATCH 0/6] writeback cleanups and trivial fixes
Date: Sun, 11 Jul 2010 10:06:56 +0800	[thread overview]
Message-ID: <20100711020656.340075560@intel.com> (raw)

Andrew,

Here are some writeback cleanups to avoid unnecessary calculation overheads,
and relative simple bug fixes.

The patch applies to latest linux-next tree. The mmotm tree will need rebase
to include commit 32422c79 (writeback: Add tracing to balance_dirty_pages)
in order to avoid merge conflicts.

[PATCH 1/6] writeback: take account of NR_WRITEBACK_TEMP in balance_dirty_pages()
[PATCH 2/6] writeback: reduce calls to global_page_state in balance_dirty_pages()
[PATCH 3/6] writeback: avoid unnecessary calculation of bdi dirty thresholds

[PATCH 4/6] writeback: dont redirty tail an inode with dirty pages
[PATCH 5/6] writeback: fix queue_io() ordering
[PATCH 6/6] writeback: merge for_kupdate and !for_kupdate cases
