Subject: [PATCH 11/49] sctp: pass a kernel pointer to sctp_setsockopt_default_send_param
Date: Thu, 21 May 2020 17:46:46 +0000 [thread overview]
Message-ID: <20200521174724.2635475-12-hch@lst.de> (raw)
In-Reply-To: <20200521174724.2635475-1-hch@lst.de>
Use the kernel pointer that sctp_setsockopt has available instead of
directly handling the user pointer.
Signed-off-by: Christoph Hellwig <hch@lst.de>
