kib 2009-01-26 14:21:00 UTC FreeBSD src repository Modified files: sys/fs/fifofs fifo_vnops.c Log: SVN rev 187715 on 2009-01-26 14:21:00Z by kib 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.
