[PATCH 2/4] blk-cgroup: correct comment for blk_alloc_queue and blk_exit_queue
Posted by Kemeng Shi 3 years, 5 months ago
Since commit 1059699f87eb("block: move blkcg initialization/destroy into
disk allocation/release handler"), blk_alloc_queue and blk_exit_queue is
called directly from gendisk. Update the corresponding comment.

Maybe be a bit more specific and say blk_alloc_disk()?
