    ieee1394: use correct barrier types between accesses of nodeid and generation · 29f8ea8a
    Stefan Richter authored
    A compiler barrier (explicit on the read side, implicit on the write
    side) is not quite enough for what has to be accomplished here.  Use
    hardware memory barriers on systems which need them.
    (Of course a full fix of generation handling would require much more
    than this.  The ieee1394 core's bus generation counter had to be tied to
    the controller's bus generation counter; cf. Kristian's stack.  It's
    just that I have other current business with the code around these
    barrier()s, so why not do at least this small fix.)
