Hi,

Is there any place where sched_clock() usage might not be safe.

 Like lets say early in the boot during driver probe ?

Or any things that i need to ensure before calling sched_clokc() ?



Thanks and regards,

Quite likely, you can't call sched_clock inside interrupt handler or similar place where interrupts are disabled or atomicity must be maintained.
