Subject: [PATCH 08/33] net: add sock_enable_timestamps
Date: Wed, 20 May 2020 21:54:44 +0200 [thread overview]
Message-ID: <20200520195509.2215098-9-hch@lst.de> (raw)
In-Reply-To: <20200520195509.2215098-1-hch@lst.de>
Add a helper to directly enable timestamps instead of setting the
SO_TIMESTAMP* sockopts from kernel space and going through a fake
uaccess.
Signed-off-by: Christoph Hellwig <hch@lst.de>
