Good idea, that. The ppc64 guys (guy) don't actually want the feature, and it significantly de-risks things. Although it's one more datapoint to be gathered when pondering oops reports. Stylistic trivia: When stubbing out a function it's cleaner (and faster) to do: #ifdef CONFIG_FOO int my_function(arg1, arg2) { ... } #else static inline int my_function(arg1, arg2) { return 0; } #endif Do we have any performance numbers on this yet? Both for speed and space? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/
