Subject: [PATCH net-next 08/10] tcp: expose __tcp_sock_set_cork and __tcp_sock_set_nodelay
From: Maxim Galaganov <max@...ernet.ru>
Expose __tcp_sock_set_cork() and __tcp_sock_set_nodelay() for use in
MPTCP setsockopt code -- namely for syncing MPTCP socket options with
subflows inside sync_socket_options() while already holding the subflow
socket lock.
