Subject: [PATCH 06/12] fuse: rework fuse_do_ioctl()
Date: Fri, 26 Oct 2012 19:49:13 +0400 [thread overview]
Message-ID: <20121026154905.18931.60765.stgit@maximpc.sw.ru> (raw)
In-Reply-To: <20121026152957.18931.46330.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.
