Code simplification (don't need both versions). Simpler kernel configuration. Even smaller .config files ;-) A useful byproduct is more reproducible crashes when the stack overruns (as 8KiB stands, it will crash the same, but only sometimes; probably even more, as it really is 6KiB for process + IRQ, and with 4KiB they are 4KiB each). Yes, more crashes is a feature, as it gets fixed faster. -- 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/
