Hi,
What's the difference between msleep_interruptible and msleep ? If I understand correctly the main difference between msleep and msleep_interruptible is that msleep_interruptible can return if there is a pending signal ?
But why if I have a kernel thread that do [1] :
while (true) { Do some stuff msleep(1000) }
the load average is high (near 100%).
and if I use msleep_interruptible the load average is normal.
Does the same applies to wait_event_timeout vs wait_event_interruptible_timeout ?
Thanks,
