Dear Scott Wood,
In message 20090904183437.GA20066@b07421-ec1.am.freescale.net you wrote:
milliseconds, i. e. a time. "(CONFIG_SYS_HZ / 4)" is a frequency, i. e. not a time, but the inverse of it.
It is plain wront to write "250 per second" when you mean "250 milliseconds"
It is not a frequency, it is a number of ticks. This is a very common idiom.
CONFIG_SYS_HZ _is_ a frequenzy. It is the number of ticks _per_ _second_. That is the _inverse_ of a time unit, not a time unit.
Best regards,
Wolfgang Denk

Misquotation is, in fact, the pride and privilege of the learned. A
widely-read man never quotes accurately, for the rather obvious
reason that he has read too widely.
