Queue is freezed while activating policy, allocate memory with queue
freezed has the risk of deadlock because memory reclaim can issue new
IO.
blk_mq_freeze_queue() already covers it by calling memalloc_noio_save(),
so this patch looks not necessary.
Yes, this can just consider a cleanup, I'll remove this if we think this
is not necessary.
Or do you have a lockdep warning?
No.
