--- Comment #2 from Konstantin Belousov <kib@FreeBSD.org> ---
We generally cannot re-init mutex that is destroyed.  It is probably fine for
the non-debugging kernels, but for kernels with WITNESS it causes some data
recorded for WITNESS book tracking.  Then unloading the module causes dandling
pointers left, and panic occurs later.
