New Revision: 227384
URL: http://svn.freebsd.org/changeset/base/227384
Log:
Simplify the code emitted by makeobjops.awk slightly.
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.
