-ENOPARSE What has the CLOCKSOURCE_MASK() to do with this and why is the fact relevant, that we only have a few suspend_nonstop clock sources? > + > +/* > + * When setting this flag, you're also supposed to mean that it doesn't > + * wrap back during system suspend/resume. See timekeeping_resume(). -ENOPARSE I guess what you want to say here is: /* * clocksource continues to run during suspend and is guaranteed not to * wrap around during long suspend periods. */ > + */ > #define CLOCK_SOURCE_SUSPEND_NONSTOP 0x80 Thanks, tglx -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
