Pull block fixes from Jens Axboe: "A set of fixes/changes that should go into this series. This contains: - Kernel doc / comment updates (Bart, Shenghui) - Un-export of core-only used function (Bart) - Fix race on loop file access (Dongli) - pf/pcd queue cleanup fixes (me) - Use appropriate helper for RESTART bit set (Yufen) - Use named identifier for classic poll (Yufen)" * tag 'for-linus-20190323' of git://git.kernel.dk/linux-block: sbitmap: trivial - update comment for sbitmap_deferred_clear_bit blkcg: Fix kernel-doc warnings blk-iolatency: #include "blk.h" block: Unexport blk_mq_add_to_requeue_list() block: add BLK_MQ_POLL_CLASSIC for hybrid poll and return EINVAL for unexpected value blk-mq: remove unused 'nr_expired' from blk_mq_hw_ctx loop: access lo_backing_file only when the loop device is Lo_bound blk-mq: use blk_mq_sched_mark_restart_hctx to set RESTART paride/pcd: cleanup queues when detection fails paride/pf: cleanup queues when detection fails
