The BUG() is still there to trap cases where we have list or
bit corruption, but I haven't been able to trigger it with
my latest patches.

What I /do/ see is lru_cache_add() getting called for pages
which are already in one of the lists. For now I simply detect
this case and work around it. I still don't know what causes
the problem, but it no longer causes any stability or data
corruption problems.

In fact, I plan to spend most of my time trying to track down
the 2 VM problems on tytso's list:

1) the innd data corruption bug
2) system hangs with 0 free low memory and some free
   high memory

The lru_cache_add() BUG() seems to be defanged for now and
isn't very high priority to me...
