Hi Paul,
This patch set removes ACCESS_ONCE() in Chapter 5.
(Yes, I saw the update in todo.txt.)
Patch #1 updates code snippets and code under CodeSamples/count/.
Patch #2 updates text in Chapter 5 as well as Section 4.2.5 to adjust
context. Citations in QQA to LWN article "ACCESS_ONCE()" is
replaced by footnotes referencing definition in Section 4.2.5.
Patch #3 adds a couple of git commits to bibliography to be cited
by Patch #4.
Patch #4 adds a Quick Quiz in Section 4.2.5 to put a brief history of
ACCESS_ONCE().
As ACCESS_ONCE() has been removed during Linux 4.15 merge window,
it would be a good chance to put some memorial words in perfbook.
In patch #4, I put them in a QQA. An alternative would be to
put them in a dedicated section on "compiler barriers" in Section 4.2 or 4.3.
In any case, the wording of the brief history needs some polishing
by the inventor of ACCESS_ONCE(). So I don't expect patch #4 to be
applied as is.
BTW, I thought twice about citing the git commit adding ACCESS_ONCE()
in RCU code because of its title. Are you OK with it being listed in
bibliography?
Thanks, Akira
