Subject: [PATCH 7/8] loop: remove extra variable in lo_req_flush
Date: Tue, 21 Sep 2021 02:21:22 -0700	[thread overview]
Message-ID: <20210921092123.13632-8-chaitanyak@nvidia.com> (raw)
In-Reply-To: <20210921092123.13632-1-chaitanyak@nvidia.com>

From: Chaitanya Kulkarni <kch@nvidia.com>

The local variable file is used to pass it to the vfs_fsync(). We can
get away with using lo->lo_backing_file instead of storing in a local
variable which is not used anywhere else.

No functional change in this patch.
