kprobes, x86: Disable irqs during optimized callback
Disable irqs during optimized callback, so we dont miss any in-irq kprobes. The following commands: # cd /debug/tracing/ # echo "p mutex_unlock" >> kprobe_events # echo "p _raw_spin_lock" >> kprobe_events # echo "p smp_apic_timer_interrupt" >> ./kprobe_events # echo 1 > events/enable Cause the optimized kprobes to be missed. None is missed with the fix applied.
