Merge tag 'for-5.19/block-2022-06-02' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "Just a collection of fixes that have been queued up since the initial merge window pull request, the majority of which are targeted for stable as well. One bio_set fix that fixes an issue with the dm adoption of cached bio structs that got introduced in this merge window" * tag 'for-5.19/block-2022-06-02' of git://git.kernel.dk/linux-block: block: Fix potential deadlock in blk_ia_range_sysfs_show() block: fix bio_clone_blkg_association() to associate with proper blkcg_gq block: remove useless BUG_ON() in blk_mq_put_tag() blk-mq: do not update io_ticks with passthrough requests block: make bioset_exit() fully resilient against being called twice block: use bio_queue_enter instead of blk_queue_enter in bio_poll block: document BLK_STS_AGAIN usage block: take destination bvec offsets into account in bio_copy_data_iter blk-iolatency: Fix inflight count imbalances and IO hangs on offline blk-mq: don't touch ->tagset in blk_mq_get_sq_hctx
