I am reading all that data from /proc/[pid]/stat and I have noticed that utime can actually go down on successive read (10 secs later in this case). How is it possible? Is this a bug or I just don't fully understand what utime is? I have kernel 2.6.30.5 if that matters. Thanks in advance for help. -- Best Regards, Piotr JaroszyƄski -- 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/
