Subject: [PATCH 6/6] fuse: rework fuse_do_ioctl()
Date: Fri, 07 Sep 2012 21:41:59 +0400 [thread overview]
Message-ID: <20120907174154.1343.22158.stgit@maximpc.sw.ru> (raw)
In-Reply-To: <20120907172536.1343.80497.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.
