Merge tag 'for-5.20/block-2022-07-29' of git://git.kernel.dk/linux-block
Pull block updates from Jens Axboe: - Improve the type checking of request flags (Bart) - Ensure queue mapping for a single queues always picks the right queue (Bart) - Sanitize the io priority handling (Jan) - rq-qos race fix (Jinke) - Reserved tags handling improvements (John) - Separate memory alignment from file/disk offset aligment for O_DIRECT (Keith) - Add new ublk driver, userspace block driver using io_uring for communication with the userspace backend (Ming) - Use try_cmpxchg() to cleanup the code in various spots (Uros) - Finally remove bdevname() (Christoph) - Clean up the zoned device handling (Christoph) - Clean up independent access range support (Christoph) - Clean up and improve block sysfs handling (Christoph) - Clean up and improve teardown of block devices. This turns the usual two step process into something that is simpler to implement and handle in block drivers (Christoph) - Clean up chunk size handling (Christoph) - Misc cleanups and fixes (Bart, Bo, Dan, GuoYong, Jason, Keith, Liu, Ming, Sebastian, Yang, Ying) * tag 'for-5.20/block-2022-07-29' of git://git.kernel.dk/linux-block: (178 commits) ublk_drv: fix double shift bug ublk_drv: make sure that correct flags(features) returned to userspace ublk_drv: fix error handling of ublk_add_dev ublk_drv: fix lockdep warning block: remove __blk_get_queue block: call blk_mq_exit_queue from disk_release for never added disks blk-mq: fix error handling in __blk_mq_alloc_disk ublk: defer disk allocation ublk: rewrite ublk_ctrl_get_queue_affinity to not rely on hctx->cpumask ublk: fold __ublk_create_dev into ublk_ctrl_add_dev ublk: cleanup ublk_ctrl_uring_cmd ublk: simplify ublk_ch_open and ublk_ch_release ublk: remove the empty open and release block device operations ublk: remove UBLK_IO_F_PREFLUSH ublk: add a MAINTAINERS entry block: don't allow the same type rq_qos add more than once mmc: fix disk/queue leak in case of adding disk failure ublk_drv: fix an IS_ERR() vs NULL check ublk: remove UBLK_IO_F_INTEGRITY ublk_drv: remove unneeded semicolon ...
