    change looks correct to me. Though I'm bit concerned about
    design choice made in this diff. see further below.

    I would prefer to move this mutex inside the struct inpcb. I know it
    makes structure larger but it looks odd to me using global mutex to
    update members which are local to structure.

    the functions in pf(4) then can manipulate the inpcb::mtx by
    dedicated functions:
	inpcb_lock(inp);
	inpcb_unlock(inp);

    just a thought. sure we can make such change as a follow up commit
    on top of your diff.

thanks and
