    Subjectdo_gettimeofday monotony?
    Is do_gettimeofday supposed to be monotonous? I'm seeing time go backward by
    tiny amounts, and then progressing.

    I'm using do_gettimeofday on a single processor, CONFIG_PREEMPT_NONE=y, and
    saving stuff from generic_make_request - see http://ds9a.nl/diskstat for the
    source. 2.6.13-rc3-mm1, HZ=250.

    I'll try to figure out how much it is going back, and it is some kind of
    magic interval.

    Is there another monotonous clock in the kernel that doesn't wrap (all
    that often)? Doesn't really need to be wall time.

    Thanks!
