I always assumed it was an optimization when looking for a new PID after a wrap by trying to skip over the kernel threads. Arguably 300 is way too small for larger systems (which might have several thousand kernel threads) and should probably be sized on boot (or when starting userspace) if anyone really cares. - 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/
