Why? With this change, if you change the version number, the file will
have to be rebuilt. Without the change, the file will not need to be
rebuilt, right?

I thought that was why this change was made a while ago, to prevent
things from having to be rebuilt that didn't need to be
I agree - what was wrong with utsname->release ... it seems odd to statically build the kernel's version
number into a module - it should be something we should be able to query (and it shouldn't change without
reboot so accessing it is not racy). Access to other fields in the structure (nodename, domainname etc.) might
need to be included in a macro but I didn't see one in utsname.h for this.
