From 91cdf265b74bf63a69949d6db08a60523207400c Mon Sep 17 00:00:00 2001 From: Minwoo Im Date: Sat, 5 Dec 2020 00:20:53 +0900 Subject: blk-mq: add helper allocating tagset->tags tagset->set is allocated from blk_mq_alloc_tag_set() rather than being reallocated. This patch added a helper to make its meaning explicitly which is to allocate rather than to reallocate.
