Is there any way to read out the compile-time HZ value of the kernel?
I had a brief look at /proc/* and didn't find anything.
The background, why it is needed:
There are certain settings, for example the icmp rate limiting values,
which can be set using sysctl. Those setting are basically derived from
HZ values (1*HZ, for example).
If you now want to set those values from a userspace program / script in
a portable manner, you need to be able to find out of HZ of the currently
running kernel.
