Subject: mptcp: pm: make three pm wrappers static
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=7aeab89b090fe40bc96e4af68c2b57f019d654d7;p=users%2Fjedix%2Flinux-maple.git

mptcp: pm: make three pm wrappers static

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.
