[PATCH] Remove unused CONFIG_LOCKMETER functions

[PATCH] Remove unused CONFIG_LOCKMETER functions

[Kirk True]

I'm working on porting SGI's lockmeter to 2.6 when I chanced upon this. I was very perplexed that it's in there since this is the only place that it appears in the codebase (according to grep).

Ray Bryant (cc'ed here) probably has a mostly-up-to-date lockmeter patch.  It
would be better to work starting from that.

You should work against the development kernel.  We've added 22MB of diff
since 2.6.11.
