Mmm. not wholly convinced that's true. Whilst i don't have lockmeter
stats to hand, the heavy time in __d_lookup seems to indicate we may
still have a problem to me. I guess we could move the spinlocks out
of line again to test this fairly easily (or get lockmeter upstream).
We definitly should get lockmeter in. Does anyone volunteer for doing
the cleanup and merged?

specifically; implementing it on top of lockdep should be very lean and
simple...
