I have recent code for that circulating, albeit intended for debugging purposes. There's nothing particularly debug-oriented about it, though, apart from the fact a guard page is automatically set up by vmalloc() and that the use of vmalloc() is unconditional. As for the rest, I'm sure there could be a lively conversation, but consensus, so I'll let it go. -- wli - 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/
