BTW, if someone enters "kernel_hz=1000", this check (above) for "100"
matches (detects) 100, not 1000.
ouch. You are right - thanks. I'll be sure to fix that.
I haven't had time to look more at this little thing for the last few
days, but I'll get back to it soon. Thank you for the feedback.
I have to admit that I like paranoid programming, and would rather see
this look for "kernel_hz=" then convert the digits after to an integer
and validate that. It would catch invalid values far better, allow other
values to be either implemented as best as is possible if desired, and
NOT ignore invalid values if they didn't match these predefined strings.
