JIRA: https://issues.redhat.com/browse/RHEL-79409 commit 1e1a9cecfab3f22ebef0a976f849c87be8d03c1c Author: Christoph Hellwig <hch@lst.de> Date: Fri Jan 31 13:03:47 2025 +0100 block: force noio scope in blk_mq_freeze_queue When block drivers or the core block code perform allocations with a frozen queue, this could try to recurse into the block device to reclaim memory and deadlock. Thus all allocations done by a process that froze a queue need to be done without __GFP_IO and __GFP_FS. Instead of tying to track all of them down, force a noio scope as part of freezing the queue. Note that nvme is a bit of a mess here due to the non-owner freezes, and they will be addressed separately.
