What is the difference with a kernel implementation? Not by being in-kernel will it make all the incompatible ways of doing this magically vanish, and give outstanding performance. Plus handling and maintaining the in-kernel stuff is _much_ harder than userspace libraries. I'd go the other way around: Get userspace to agree on a common framework, make it work in userspace; if (extensive, hopefully) experience shows that a pure userspace solution has issues that can't be solved except by kernel assistance, so be it. -- Dr. Horst H. von Brand User #22616 counter.li.org Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513 - 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/
