Subject: [PATCH] block: don't remove hctx debugfs dir from blk_mq_exit_queue
Git-commit: de3d347f7b8a1a997fbc9267454ed6065068b969
Patch-mainline: v5.18-rc1
References: jsc#PED-1183
The queue's top debugfs dir is removed from blk_release_queue(), so all
hctx's debugfs dirs are removed from there. Given blk_mq_exit_queue()
is only called from blk_cleanup_queue(), it isn't necessary to remove
hctx debugfs from blk_mq_exit_queue().
So remove it from blk_mq_exit_queue().
