Subject: [PATCH 04/15] iomap: warn on inline maps iomap_writepage_map
Date: Mon, 1 Jul 2019 23:54:28 +0200 [thread overview]
Message-ID: <20190701215439.19162-5-hch@lst.de> (raw)
In-Reply-To: <20190701215439.19162-1-hch@lst.de>
And inline mapping should never mark the page dirty and thus never end up
in writepages. Add a check for that condition and warn if it happens.
