a simple way to get rid of this:

        struct timespec uptime;
        struct timespec idle;
        int len;
        cputime_t idletime;

+	if (off)

Except that this is wrong - if you try to advance the offset a bit from the start of the file and read something, you'll get nothing. This is inconsistent with normal file behavior.
