Would you all consider it acceptable to disallow watchpoints on per cpu data entirely? I can think of a *lot* of places where hitting #DB when accessing per cpu data from entry asm would be bad. Of course, actually implementing that might be less than entirely fun, given that a cpu could be onlined after creating a watchpoint. --Andy -- Andy Lutomirski AMA Capital Management, LLC -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
