Subject: [PATCH v6 06/19] gfs2: Add wrapper for iomap_file_buffered_write
Date: Thu, 19 Aug 2021 21:40:49 +0200 [thread overview]
Message-ID: <20210819194102.1491495-7-agruenba@redhat.com> (raw)
In-Reply-To: <20210819194102.1491495-1-agruenba@redhat.com>
Add a wrapper around iomap_file_buffered_write. We'll add code for when
the operation needs to be retried here later.
Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
