Lots of things we do because we just assume they're a good idea without any evidence. Renicing kernel threads was always considered a good idea on this basis. I'm certain noone has ever proven that it's a good thing though. Either way, the latest version of rsdl is robust enough that it works fine with reniced kernel threads if you still believe that's advantageous. This is definitely open for discussion/opinion. -- -ck - 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/
