Name:Check to see if this CPU is in a non-context-switch quiescent state,* namely user mode and idle loop.

Proto:static void rcu_flavor_sched_clock_irq(int user)

Type:void

Parameter:

TypeParameterName
intuser
904  If user || _is_cpu_rrupt_from_idle - see if interrupted from idle* If the current CPU is idle and running at a first-level (not nested)* interrupt from idle, return true. The caller must have at least* disabled preemption. Then
918  Note a quiescent state for PREEMPT=n. Because we do not need to know* how many quiescent states passed, just if there was at least one since* the start of the grace period, this just sets a flag. The caller must* have disabled preemption.
