Subject: [PATCH 2/4] memremap: remove the dev field in struct dev_pagemap
Date: Fri, 16 Aug 2019 08:54:32 +0200 [thread overview]
Message-ID: <20190816065434.2129-3-hch@lst.de> (raw)
In-Reply-To: <20190816065434.2129-1-hch@lst.de>
The dev field in struct dev_pagemap is only used to print dev_name in
two places, which are at best nice to have. Just remove the field
and thus the name in those two messages.
