Subject: Re: [Ocfs2-devel] [PATCH v7 16/19] iomap: Add done_before argument to iomap_dio_rw
Date: Thu, 9 Sep 2021 12:30:45 +0100	[thread overview]
Message-ID: <YTnwZU8Q0eqBccmM@infradead.org> (raw)
In-Reply-To: <20210827164926.1726765-17-agruenba@redhat.com>

What about just passing done_before as an argument to
iomap_dio_complete? gfs2 would have to switch to __iomap_dio_rw +
iomap_dio_complete instead of iomap_dio_rw for that, and it obviously
won't work for async completions, but you force sync in this case
anyway, right?
