Subject: [PATCH 7/7] btrfs: remove local blocksize variable in reada_find_extent
Date: Wed, 15 Mar 2017 17:02:42 +0100	[thread overview]
Message-ID: <9355f3bb85dcdb05a30ad8f7e11bedae2f08afb0.1489593696.git.dsterba@suse.com> (raw)
In-Reply-To: <cover.1489593696.git.dsterba@suse.com>

The name is misleading and the local variable serves no purpose.
