Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Browse Source 
Pull more block fixes from Jens Axboe:
 "As mentioned in the pull the other day, a few more fixes for this
  round, all related to the bio op changes in this series.

  Two fixes, and then a cleanup, renaming bio->bi_rw to bio->bi_opf.  I
  wanted to do that change right after or right before -rc1, so that
  risk of conflict was reduced.  I just rebased the series on top of
  current master, and no new ->bi_rw usage has snuck in"

* 'for-linus' of git://git.kernel.dk/linux-block:
  block: rename bio bi_rw to bi_opf
  target: iblock_execute_sync_cache() should use bio_set_op_attrs()
  mm: make __swap_writepage() use bio_set_op_attrs()
  block/mm: make bdev_ops->rw_page() take a bool for read/write

@ -269,7 +269,7 @@ Arjan's proposed request priority scheme allows higher levels some broad
requests which haven't aged too much on the queue. Potentially this priority
could even be exposed to applications in some manner, providing higher level
tunability. Time based aging avoids starvation of lower priority
requests. Some bits in the bi_rw flags field in the bio structure are
requests. Some bits in the bi_opf flags field in the bio structure are
intended to be used for this priority information.
