I suspect that this thread is a root cause of the problem. In this place, the vnode should be freshly created and not visible to anything but the current thread. So, vn_lock() should always immediately succeed. I cannot understand how the vnode lock could be held by another thread. -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
