  "message": "blk-mq: Allow blocking queue tag iter callbacks\n\ncommit 530ca2c9bd6949c72c9b5cfc330cb3dbccaa3f5b upstream.\n\nA recent commit runs tag iterator callbacks under the rcu read lock,\nbut existing callbacks do not satisfy the non-blocking requirement.\nThe commit intended to prevent an iterator from accessing a queue that\u0027s\nbeing modified. This patch fixes the original issue by taking a queue\nreference instead of reading it, which allows callbacks to make blocking\ncalls.\n\nFixes: f5bbbbe4d6357 (\"blk-mq: sync the update nr_hw_queues with blk_mq_queue_tag_busy_iter\")\nAcked-by: Jianchao Wang \u003cjianchao.w.wang@oracle.com\u003e\nSigned-off-by: Keith Busch \u003ckeith.busch@intel.com\u003e\nSigned-off-by: Jens Axboe \u003caxboe@kernel.dk\u003e\nSigned-off-by: Giuliano Procida \u003cgprocida@google.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n",
