Subject: [PATCH net-next 5/7] tcp: export timestamp helpers for mptcp
Date: Thu, 3 Jun 2021 16:24:31 -0700 [thread overview]
Message-ID: <20210603232433.260703-6-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20210603232433.260703-1-mathew.j.martineau@linux.intel.com>
From: Florian Westphal <fw@strlen.de>
MPTCP is builtin, so no need to add EXPORT_SYMBOL()s.
It will be used to support SO_TIMESTAMP(NS) ancillary
messages in the mptcp receive path.
Acked-by: Paolo Abeni <pabeni@redhat.com>
