Log message:
Passing M_WAITOK to mbuf functions is supposed to be a contract between
the caller and the function that the function will not fail to allocate
memory and return a NULL pointer. However, m_dup_pkthdr() violates
this contract, making it possible for functions that pass M_WAITOK to
be surprised in ways that hurt.
Fix this by passing the wait flag all the way down the functions that
actually do the allocation for m_dup_pkthdr() so that we won't be
surprised.
man page update forthcoming
