Merge tag 'for-5.4/post-2019-09-24' of git://git.kernel.dk/linux-block
Pull more block updates from Jens Axboe: "Some later additions that weren't quite done for the first pull request, and also a few fixes that have arrived since. This contains: - Kill silly pktcdvd warning on attempting to register a non-scsi passthrough device (me) - Use symbolic constants for the block t10 protection types, and switch to handling it in core rather than in the drivers (Max) - libahci platform missing node put fix (Nishka) - Small series of fixes for BFQ (Paolo) - Fix possible nbd crash (Xiubo)" * tag 'for-5.4/post-2019-09-24' of git://git.kernel.dk/linux-block: block: drop device references in bsg_queue_rq() block: t10-pi: fix -Wswitch warning pktcdvd: remove warning on attempting to register non-passthrough dev ata: libahci_platform: Add of_node_put() before loop exit nbd: fix possible page fault for nbd disk nbd: rename the runtime flags as NBD_RT_ prefixed block, bfq: push up injection only after setting service time block, bfq: increase update frequency of inject limit block, bfq: reduce upper bound for inject limit to max_rq_in_driver+1 block, bfq: update inject limit only after injection occurred block: centralize PI remapping logic to the block layer block: use symbolic constants for t10_pi type
