[PATCH 0/2] futex: updates for hb waiters

[Davidlohr Bueso]

Since we recently changed the way we account for pending waiters
back to the atomic ops variant, we can do some minor updates to
the code. The first is a necessary doc change, and the other a
small helper function. 

Please consider for 3.15.

Davidlohr Bueso (2):
  futex: update comments for ordering guarantees
  futex: add plist_del + atomic_dec helper
