Subject: [PATCH net-next 3/4] mptcp: unify pm get_flags_and_ifindex_by_id
Date: Thu, 08 Jun 2023 15:20:51 +0200 [thread overview]
Message-ID: <20230608-upstream-net-next-20230608-mptcp-unify-pm-interfaces-v1-3-b301717c9ff5@tessares.net> (raw)
In-Reply-To: <20230608-upstream-net-next-20230608-mptcp-unify-pm-interfaces-v1-0-b301717c9ff5@tessares.net>
From: Geliang Tang <geliang.tang@suse.com>
This patch unifies the three PM get_flags_and_ifindex_by_id() interfaces:
mptcp_pm_nl_get_flags_and_ifindex_by_id() in mptcp/pm_netlink.c for the
in-kernel PM and mptcp_userspace_pm_get_flags_and_ifindex_by_id() in
mptcp/pm_userspace.c for the userspace PM.
They'll be switched in the common PM infterface
mptcp_pm_get_flags_and_ifindex_by_id() in mptcp/pm.c based on whether
mptcp_pm_is_userspace() or not.
