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