mutex. - Don't use callout_drain() to stop the toffhandle callout while holding the fdc mutex (this could deadlock) in functions called from softclock (callouts aren't allowed to do voluntary sleeps). Instead, use callout_stop(). Note that since we hold the associated mutex and are now using callout_init_mtx(), callout_stop() is just as effective as callout_drain(). (Though callout_drain() is still needed in detach to make sure softclock isn't contesting on our mutex before we destroy the mutex.) - Remove unused callout 'tohandle' from softc. MFC after: 1 week |
