The comment still applies to this block of code.

Just place the default kobj_method inside the kobjop_desc structure.
There's no need to give these kobj_methods their own symbol. This shaves
off 10 KB of a GENERIC kernel binary.

These structures hold no information that is modified during runtime. By
marking this constant, we see approximately 600 symbols become
read-only (amd64 GENERIC). While there, also mark the kobj_method
structures generated by makeobjops.awk static. They are only referenced
by the kobjop_desc structures within the same file.
Before:

it keeps asking you if you want to overwrite it or not.

Note the invocation ordering is slightly different:
awk -f makeobjops.awk foo.m -ch
