Subject: [PATCH 7/7] ps3disk: handle highmem pages
Date: Wed,  9 May 2018 15:59:48 +0200	[thread overview]
Message-ID: <20180509135948.20329-8-hch@lst.de> (raw)
In-Reply-To: <20180509135948.20329-1-hch@lst.de>

The ps3disk driver already kmaps all pages when copying from/to the
internal bounce buffer, so it can accept highmem pages just fine.
