Commit 180dccb0dba4f ("blk-mq: fix tag_get wait task can't be awakened") added wake_batch recalculation when user number of shared tags changes to avoid hung as user number increases, then hctx_max_depth limit for a single user decreases and may trigger hung if wake_batch > hctx_max_depth is met. Commit 285008501c65a ("blk-mq: always allow reserved allocation in hctx_may_queue") removed hctx_max_depth limit to alloc reserved tags, so hctx_max_depth limit for reserved tags is not exisiting anymore so we can remove recalculation for reserved tags.
