<title>workqueue: Rename "delayed" (delayed by active management) to "inactive"</title>

<id>urn:sha1:f97a4a1a3f8769e3452885967955e21c88f3f263</id>
<content type='text'>
There are two kinds of "delayed" work items in workqueue subsystem.

One is for timer-delayed work items which are visible to workqueue users.
The other kind is for work items delayed by active management which can
not be directly visible to workqueue users.  We mixed the word "delayed"
for both kinds and caused somewhat ambiguity.

This patch renames the later one (delayed by active management) to
"inactive", because it is used for workqueue active management and
most of its related symbols are named with "active" or "activate".

All "delayed" and "DELAYED" are carefully checked and renamed one by
one to avoid accidentally changing the name of the other kind for
timer-delayed.

No functional change intended.

The return values of workqueue_init() and workqueue_early_int() are
always 0, and there is no usage of their return value.  So just make
them return void.

<title>workqueue: Document (some) memory-ordering properties of {queue,schedule}_work()</title>

<id>urn:sha1:dbb92f88648d6206bf22fcb764fb9fe2939d401a</id>

It's desirable to be able to rely on the following property:  All stores
preceding (in program order) a call to a successful queue_work() will be
visible from the CPU which will execute the queued work by the time such
work executes, e.g.,

  { x is initially 0 }

    CPU0                              CPU1

    WRITE_ONCE(x, 1);                 [ "work" is being executed ]
    r0 = queue_work(wq, work);          r1 = READ_ONCE(x);

  Forbids: r0 == true &amp;&amp; r1 == 0

The current implementation of queue_work() provides such memory-ordering
property:

  - In __queue_work(), the -&gt;lock spinlock is acquired.

  - On the other side, in worker_thread(), this same -&gt;lock is held
    when dequeueing work.

So the locking ordering makes things work out.

Add this property to the DocBook headers of {queue,schedule}_work().

padata will use these these interfaces in a later patch, so unconfine them.
