39 Neither plain C-language accesses nor data_race() (#1 and #2 above) place
45 preferable to data_race(), which in turn is usually preferable to plain
47 data_race(READ_ONCE(a)), which will both restrict compiler optimizations
52 race with one of data_race(), READ_ONCE(), or WRITE_ONCE(), will prevent
56 ill-considered additions of data_race(), READ_ONCE(), and WRITE_ONCE()
60 data_race() and even plain C-language accesses is preferable to
64 Use of the data_race() Macro
