Hi Thomas,
I found this piece of code in tick-oneshot.c:
+int tick_oneshot_mode_active(void)
+{
+ unsigned long flags;
+ int ret;
+
+ local_irq_save(flags);
+ ret = __get_cpu_var(tick_cpu_device).mode == TICKDEV_MODE_ONESHOT;
+ local_irq_restore(flags);
+
+ return ret;
+}
Why do we need local_irq_save/restore() here for just reading value
of this variable? Can these be dropped? If yes, I would do that as
part of my cleanup series around tick stuff.
