Subject: [PATCH V2 6/8] loop: remove extra variable in lo_fallocate()
Date: Wed, 22 Sep 2021 18:49:43 -0700 [thread overview]
Message-ID: <20210923014945.6229-7-chaitanyak@nvidia.com> (raw)
In-Reply-To: <20210923014945.6229-1-chaitanyak@nvidia.com>
From: Chaitanya Kulkarni <kch@nvidia.com>
The local variable q is used to pass it to the blk_queue_discard(). We
can get away with using lo->lo_queue instead of storing in a local
variable which is not used anywhere else.
No functional change in this patch.
