Log:
SVN rev 188389 on 2009-02-09 12:22:49Z by kib
MFC r187715:
The kernel may do unbalanced calls to fifo_close() for fifo vnode,
without corresponding number of fifo_open(). This causes assertion
failure in fifo_close() due to vp->v_fifoinfo being NULL for kernel
with INVARIANTS, or NULL pointer dereference otherwise. In fact, we may
ignore excess calls to fifo_close() without bad consequences.
Turn KASSERT() into the return, and print warning for now.
