I bet you didn't expect that.
Our header files suck.

This should have been done in the first place, IMO. Avoid header file
dependencies, faster compile, avoid crap like the above.

Should I be removing all references to NFSD_TCP in the patch that
removes NFSD_TCP? That would mean touching 90 config files under arch.

Nope. They will slowly disappear over time as maintainers refresh their
defconfigs.

OK. So as a general rule, we should skip the include any time when a
few structure declarations would suffice?
Hm. It also seems wrong that sys_ia32.c would need to include so many
nfsd/sunrpc headers. It looks like that should be easy to fix with a
better organization of the nfsd headers--I'll do that, assuming it's
considered worthwhile....

Yes. Unessecary includes should always be avoided, and forward
declarations are a nice way to avoid includes.

Why does it need to include either of these at all? There's nothing
nfs-specific in that file.

That implies maintainers actually maintaining it. When did we get the
last real update (nto just removeing dead options) to the 32bit x86
defconfig?

The last one I recall was in July 2006 when someone set the SUSPEND
partition in defconfig and machines without that partition existing
would panic on bootup.
