Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull more block updates from Jens Axboe: "This is a followup for block changes, that didn't make the initial pull request. It's a bit of a mixed bag, this contains: - A followup pull request from Sagi for NVMe. Outside of fixups for NVMe, it also includes a series for ensuring that we properly quiesce hardware queues when browsing live tags. - Set of integrity fixes from Dmitry (mostly), fixing various issues for folks using DIF/DIX. - Fix for a bug introduced in cciss, with the req init changes. From Christoph. - Fix for a bug in BFQ, from Paolo. - Two followup fixes for lightnvm/pblk from Javier. - Depth fix from Ming for blk-mq-sched. - Also from Ming, performance fix for mtip32xx that was introduced with the dynamic initialization of commands" * 'for-linus' of git://git.kernel.dk/linux-block: (44 commits) block: call bio_uninit in bio_endio nvmet: avoid unneeded assignment of submit_bio return value nvme-pci: add module parameter for io queue depth nvme-pci: compile warnings in nvme_alloc_host_mem() nvmet_fc: Accept variable pad lengths on Create Association LS nvme_fc/nvmet_fc: revise Create Association descriptor length lightnvm: pblk: remove unnecessary checks lightnvm: pblk: control I/O flow also on tear down cciss: initialize struct scsi_req null_blk: fix error flow for shared tags during module_init block: Fix __blkdev_issue_zeroout loop nvme-rdma: unconditionally recycle the request mr nvme: split nvme_uninit_ctrl into stop and uninit virtio_blk: quiesce/unquiesce live IO when entering PM states mtip32xx: quiesce request queues to make sure no submissions are inflight nbd: quiesce request queues to make sure no submissions are inflight nvme: kick requeue list when requeueing a request instead of when starting the queues nvme-pci: quiesce/unquiesce admin_q instead of start/stop its hw queues nvme-loop: quiesce/unquiesce admin_q instead of start/stop its hw queues nvme-fc: quiesce/unquiesce admin_q instead of start/stop its hw queues ...
