Subject: blk-mq: move update of tags->rqs to __blk_mq_alloc_request()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=562bef4259776c19cb2423d43af1f99183910a4d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

blk-mq: move update of tags->rqs to __blk_mq_alloc_request()

No functional difference, it just makes a little more sense to update
the tag map where we actually allocate the tag.
