I'm not just concerned about the ati driver. There's a lot of driver that do or did really stupid stuff with mmap, including in-tree drivers. the actual mmap() code is not actually a fastpath so additional sanity checks can't hurt. It might not be worth the effort for ->nopage, though. - 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/
