Merge tag 'for-linus-20190809' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: - Revert of a bcache patch that caused an oops for some (Coly) - ata rb532 unused warning fix (Gustavo) - AoE kernel crash fix (He) - Error handling fixup for blkdev_get() (Jan) - libata read/write translation and SFF PIO fix (me) - Use after free and error handling fix for O_DIRECT fragments. There's still a nowait + sync oddity in there, we'll nail that start next week. If all else fails, I'll queue a revert of the NOWAIT change. (me) - Loop GFP_KERNEL -> GFP_NOIO deadlock fix (Mikulas) - Two BFQ regression fixes that caused crashes (Paolo) * tag 'for-linus-20190809' of git://git.kernel.dk/linux-block: bcache: Revert "bcache: use sysfs_match_string() instead of __sysfs_match_string()" loop: set PF_MEMALLOC_NOIO for the worker thread bdev: Fixup error handling in blkdev_get() block, bfq: handle NULL return value by bfq_init_rq() block, bfq: move update of waker and woken list to queue freeing block, bfq: reset last_completed_rq_bfqq if the pointed queue is freed block: aoe: Fix kernel crash due to atomic sleep when exiting libata: add SG safety checks in SFF pio transfers libata: have ata_scsi_rw_xlat() fail invalid passthrough requests block: fix O_DIRECT error handling for bio fragments ata: rb532_cf: Fix unused variable warning in rb532_pata_driver_probe
