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
