[PATCH 0/1] lockdep: fix warning: print_lock_trace defined but not used

[john . hubbard]

From: John Hubbard <jhubbard@xxxxxxxxxx>

Hi,

This is a second attempt to send this. The first attempt [1]
went via mailgw.nvidia.com, and did not receive a DKIM signature,
so I think it probably got discarded by many systems.

This one goes via gmail, which is what I was using before. We'll keep
working on getting the NVIDIA outgoing email servers working
with mailing lists, but meanwhile I'm back to using "envelope"
techniques, I guess. I was hoping to use a "native" email
address, but not quite there yet. :)

Anyway, here's the original cover letter:

I ran across this minor warning while building against today's linux.git.

The proposed trivial fix leaves it a little fragile from a "what if someone
adds a new call to print_lock_trace()" point of view, but I believe that it
makes the current combination of ifdefs accurate, anyway.
