The kernel can even customize the page at runtime if it needs to, such as changing algorithims to deal with lock contention.
Of course, this page will need to present a stable interface to glibc, and having both the code and a comprehensive jump-table might become tough in a single page... - 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/
