Subject: [PATCH 06/11] fuse: rework fuse_do_ioctl()
Date: Wed, 19 Sep 2012 20:32:37 +0400 [thread overview]
Message-ID: <20120919163230.29482.61000.stgit@maximpc.sw.ru> (raw)
In-Reply-To: <20120919161559.29482.55120.stgit@maximpc.sw.ru>
fuse_do_ioctl() already calculates the number of pages it's going to use. It is
stored in 'num_pages' variable. So the patch simply uses it for allocating
fuse_req.
