Yes, it is mentioned for those which did change it back in the days  
where it didn't changed anything in glibc and updated to fc4. lang/icc  
was a bit picky about the compat.linux.* sysctls a little bit longer.

Anyone with enough mdoc-fu listening for the linux(4) change?

The 2.6 code is an extension to the 2.4 code. The 2.6 one is needed  
for newer FC releases. So the current sysctl stuff is just a disabling  
of some code in some syscalls. The goal is get stable 2.6 extensions  
and to forget about the 2.4 downgrade (removing the part which  
disables some stuff currently, the rest is needed).

So no need to document the effects of some specific values for  
osrelease, it's enough to say that only the default is supported, a  
non default value may cause unwanted behavior and bugreports should be  
submitted with default values.

Bye,
Alexander.
