Think about a threaded process that gets time on multiple processors and then compares the times. This means that the time value obtained later on one thread may indicate a time earlier than that obtained on another thread. An essential requirement for time values is that they are monotonically increasing. You are changing that basic nature. > boot/run time tunable to set this min_delta if there's no good way to > calculate it.

IA64 asm instructions bundling and cycle optimization will have to be changed. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
