    Julia reported that the document looked unfinished, and it is. I
    forgot to include the example cooked up by Paul here:

    https://lkml.kernel.org/r/20170731174345.GL3730@linux.vnet.ibm.com

    and I added an explicit example showing how, while it is an ACQUIRE
    pattern, it really does provide an MB.

  • 706eeb3e9   Documentation/locking/atomic: Add documents for new atomic_t APIs ... Browse Code »

    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    existing documentation is woefully out of date and people seem to get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
    affairs.

    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.
