    Documentation/locking/atomic: Add documents for new atomic_t APIs · 706eeb3e
    Peter Zijlstra authored
    Since we've vastly expanded the atomic_t interface in recent years the
    existing documentation is woefully out of date and people seem to get
    confused a bit.
    Start a new document to hopefully better explain the current state of
    The old atomic_ops.txt also covers bitmaps and a few more details so
    this is not a full replacement and we'll therefore keep that document
    around until such a time that we've managed to write more text to cover
    its entire.
    Also please, ReST people, go away.
