AFAICS struct work_struct already includes a timer, and
linux/workqueue.h provides schedule_delayed_work() /
cancel_rearming_delayed_work() to use it, so we can switch to using
those instead of maintaining our own timer.  I'm about to do just that
to cxacru.

BTW what do you think about using our own workqueue?  I guess keventd
won't tolerate suspending for two seconds, as is possible with current
status polling routines both in speedtch and cxacru, which you've
pointed out some time ago.

Cheers,
