How serious is the 1/HZ = sane problem, and more to the point how
many programs get the HZ value with a system call as opposed to
including a header or building it in? I know some of my older
programs use header files, that was part of the planning for the
future even before 2.5 started. At the time I didn't expect to have
to use the system call.
in binary 1/100 or 1/1000 are not sane values to start with so I don't
think that that this is likly to be that critical (remembering that
the kernel doesn't do floating point math)
The kernel isn't the issue, it's programs which do timing and get values
in ticks which they convert to time by dividing by HZ. I at least get
that from a header, proper way would be with the syscall.
