mptcp: fix bad RCVPRUNED mib accounting
commit 0a567c2a10033bf04ed618368d179bce6977984b upstream. Since its introduction, the mentioned MIB accounted for the wrong event: wake-up being skipped as not-needed on some edge condition instead of incoming skb being dropped after landing in the (subflow) receive queue. Move the increment in the correct location. Fixes: ce599c51 ("mptcp: properly account bulk freed memory") Cc: stable@vger.kernel.org Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Mat Martineau <martineau@kernel.org> Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com> [ Conflicts in protocol.c, because the commit 6511882c ("mptcp: allocate fwd memory separately on the rx and tx path") is not in this version. The fix can still be applied before the 'goto drop'. ] Signed-off-by: Matthieu Baerts (NGI0) <matttbe@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
