299 *
300 * No data-dependent reads from memory-like regions are ever reordered
301 * over this barrier. All reads preceding this primitive are guaranteed
302 * to access memory (but not necessarily other CPUs' caches) before any
303 * reads following this primitive that depend on the data return by
304 * any of the preceding reads. This primitive is much lighter weight than
305 * rmb() on most CPUs, and is never heavier weight than is
306 * rmb().
307 *
308 * These ordering constraints are respected by both the local CPU
309 * and the compiler.
310 *
311 * Ordering is not guaranteed by anything other than these primitives,
312 * not even by data dependencies. See the documentation for
313 * memory_barrier() for examples and URLs to more information.
314 *
315 * For example, the following code would force ordering (the initial
316 * value of "a" is zero, "b" is one, and "p" is "&a"):
317 *
318 * <programlisting>
319 * CPU 0 CPU 1
320 *
321 * b = 2;
322 * memory_barrier();
323 * p = &b; q = p;
324 * read_barrier_depends();
325 * d = *q;
326 * </programlisting>
327 *
328 *
329 * because the read of "*q" depends on the read of "p" and these
330 * two reads are separated by a read_barrier_depends(). However,
331 * the following code, with the same initial values for "a" and "b":
332 *
333 * <programlisting>
334 * CPU 0 CPU 1
335 *
336 * a = 2;
337 * memory_barrier();
338 * b = 3; y = b;
339 * read_barrier_depends();
340 * x = a;
341 * </programlisting>
342 *
343 * does not enforce ordering, since there is no data dependency between
344 * the read of "a" and the read of "b". Therefore, on some CPUs, such
345 * as Alpha, "y" could be set to 3 and "x" to 0. Use rmb()
346 * in cases like this where there are no data dependencies.
