--- Comment #5 from Mark Johnston <ma...@freebsd.org> ---
Whether the lock is held doesn't really matter. At this point the driver owns
the mbuf. The lock only protects driver state, so if, say, it updates a
descriptor to point to the mbuf buffer, we'd want to ensure that the pointer is
cleared before the mbuf is freed or handed off to other layers. But the actual
m_freem() call does not require any synchronization.
