Subject: [PATCH net 0/2] mptcp: Locking fixes

Two separate locking fixes for the networking tree:

Patch 1 addresses a MPTCP fastopen error-path deadlock that was found
with syzkaller.

Patch 2 works around a lockdep false-positive between MPTCP listening and
non-listening sockets at socket destruct time.


Paolo Abeni (2):
  mptcp: fix deadlock in fastopen error path
  mptcp: fix lockdep false positive
