From c76c6956566f974bac2470bd72fc22fb923e04a1 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Mon, 14 Sep 2020 10:01:18 +0200 Subject: mptcp: call tcp_cleanup_rbuf on subflows That is needed to let the subflows announce promptly when new space is available in the receive buffer. tcp_cleanup_rbuf() is currently a static function, drop the scope modifier and add a declaration in the TCP header.
