[NeilBrown]

This series has the fixes for the recently reported performance
regressions merged into the patches which caused them.
It also has a couple of little fixes that have been mentioned on the
list, and that Jeff had merged into his copy.

Thanks,
NeilBrown

      fs/locks: use properly initialized file_lock when unlocking.
      fs/locks: allow a lock request to block other requests.
