Subject: [PATCH net-next v2 09/15] mptcp: pm: make three pm wrappers static
From: Geliang Tang <tanggeliang@...inos.cn>
Three netlink functions:
mptcp_pm_nl_get_addr_doit()
mptcp_pm_nl_get_addr_dumpit()
mptcp_pm_nl_set_flags_doit()
are generic, implemented for each PM, in-kernel PM and userspace PM. It's
clearer to move them from pm_netlink.c to pm.c.
And the linked three path manager wrappers
mptcp_pm_get_addr()
mptcp_pm_dump_addr()
mptcp_pm_set_flags()
can be changed as static functions, no need to export them in protocol.h.
