Perhaps we can define something like:
#ifdef CONFIG_HAS_RAW_IRQS_DISABLED_FLAGS
# define test_irqs_disabled_flags(flags) raw_irqs_disabled_flags(flags)
#else
# define test_irqs_disabled_flags(flags) \
({ (void)flags; irqs_disabled();})
#endif
then we could do
if (test_irqs_disabled_flags(flags) && wake_klogd)
wake_up_klogd();
Or is this asking too much ;-)
