Merge tag 'for-6.1/block-2022-10-03' of git://git.kernel.dk/linux
Pull block updates from Jens Axboe: - NVMe pull requests via Christoph: - handle number of queue changes in the TCP and RDMA drivers (Daniel Wagner) - allow changing the number of queues in nvmet (Daniel Wagner) - also consider host_iface when checking ip options (Daniel Wagner) - don't map pages which can't come from HIGHMEM (Fabio M. De Francesco) - avoid unnecessary flush bios in nvmet (Guixin Liu) - shrink and better pack the nvme_iod structure (Keith Busch) - add comment for unaligned "fake" nqn (Linjun Bao) - print actual source IP address through sysfs "address" attr (Martin Belanger) - various cleanups (Jackie Liu, Wolfram Sang, Genjian Zhang) - handle effects after freeing the request (Keith Busch) - copy firmware_rev on each init (Keith Busch) - restrict management ioctls to admin (Keith Busch) - ensure subsystem reset is single threaded (Keith Busch) - report the actual number of tagset maps in nvme-pci (Keith Busch) - small fabrics authentication fixups (Christoph Hellwig) - add common code for tagset allocation and freeing (Christoph Hellwig) - stop using the request_queue in nvmet (Christoph Hellwig) - set min_align_mask before calculating max_hw_sectors (Rishabh Bhatnagar) - send a rediscover uevent when a persistent discovery controller reconnects (Sagi Grimberg) - misc nvmet-tcp fixes (Varun Prakash, zhenwei pi) - MD pull request via Song: - Various raid5 fix and clean up, by Logan Gunthorpe and David Sloan. - Raid10 performance optimization, by Yu Kuai. - sbitmap wakeup hang fixes (Hugh, Keith, Jan, Yu) - IO scheduler switching quisce fix (Keith) - s390/dasd block driver updates (Stefan) - support for recovery for the ublk driver (ZiyangZhang) - rnbd drivers fixes and updates (Guoqing, Santosh, ye, Christoph) - blk-mq and null_blk map fixes (Bart) - various bcache fixes (Coly, Jilin, Jules) - nbd signal hang fix (Shigeru) - block writeback throttling fix (Yu) - optimize the passthrough mapping handling (me) - prepare block cgroups to being gendisk based (Christoph) - get rid of an old PSI hack in the block layer, moving it to the callers instead where it belongs (Christoph) - blk-throttle fixes and cleanups (Yu) - misc fixes and cleanups (Liu Shixin, Liu Song, Miaohe, Pankaj, Ping-Xiang, Wolfram, Saurabh, Li Jinlin, Li Lei, Lin, Li zeming, Miaohe, Bart, Coly, Gaosheng * tag 'for-6.1/block-2022-10-03' of git://git.kernel.dk/linux: (162 commits) sbitmap: fix lockup while swapping block: add rationale for not using blk_mq_plug() when applicable block: adapt blk_mq_plug() to not plug for writes that require a zone lock s390/dasd: use blk_mq_alloc_disk blk-cgroup: don't update the blkg lookup hint in blkg_conf_prep nvmet: don't look at the request_queue in nvmet_bdev_set_limits nvmet: don't look at the request_queue in nvmet_bdev_zone_mgmt_emulate_all blk-mq: use quiesced elevator switch when reinitializing queues block: replace blk_queue_nowait with bdev_nowait nvme: remove nvme_ctrl_init_connect_q nvme-loop: use the tagset alloc/free helpers nvme-loop: store the generic nvme_ctrl in set->driver_data nvme-loop: initialize sqsize later nvme-fc: use the tagset alloc/free helpers nvme-fc: store the generic nvme_ctrl in set->driver_data nvme-fc: keep ctrl->sqsize in sync with opts->queue_size nvme-rdma: use the tagset alloc/free helpers nvme-rdma: store the generic nvme_ctrl in set->driver_data nvme-tcp: use the tagset alloc/free helpers nvme-tcp: store the generic nvme_ctrl in set->driver_data ...
