Subject: [PATCH 3/6] nouveau: remove the block parameter to nouveau_range_fault
Date: Mon, 22 Jul 2019 11:44:23 +0200 [thread overview]
Message-ID: <20190722094426.18563-4-hch@lst.de> (raw)
In-Reply-To: <20190722094426.18563-1-hch@lst.de>
The parameter is always false, so remove it as well as the -EAGAIN
handling that can only happen for the non-blocking case.
Signed-off-by: Christoph Hellwig <hch@lst.de>
