This comes to mind:
if (cv_timedwait_sig(cv, mtx, ddi_get_lbolt()) == 0)
/* signal pending */
but my mind rings 'hacky' bells on seeing this ...
The low-level method, outside of DDI, exists of course, ISSIG() and
related macros ...
Why do you need to know this in a driver, how should behaviour be
different ?
