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

 fs/fs-writeback.c         |   68 ++++-----------
 include/linux/writeback.h |    5 -
 mm/backing-dev.c          |    3
