Subject: [PATCH 15/15] afs: Use find_get_pages_range_tag()
Date: Wed, 27 Sep 2017 18:03:34 +0200 [thread overview]
Message-ID: <20170927160334.29513-16-jack@suse.cz> (raw)
In-Reply-To: <20170927160334.29513-1-jack@suse.cz>
Use find_get_pages_range_tag() in afs_writepages_region() as we are
interested only in pages from given range. Remove unnecessary code after
this conversion.
