I don't think you are suppose to leave the kernel with mutex(es) held. A mutex is a short term lock, and at best you are abusing it's intended use. Moreover, I don't think you should leave the kernel with _any_ kernel synchronization object held. In the case of the mutex, the thread performing the close() may not be the thread that did the open() and which owns the mutex. -- DE _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
