[GIT PULL] workqueue [delayed_]work_pending() cleanups for 3.9-rc1

[Tejun Heo]

Hello, Linus.

This is part of on-going cleanups to remove / minimize usages of
workqueue interfaces which are deprecated and/or misleading.  This
round drops a number of usages of [delayed_]work_pending(), which are
dangerous as they lack any form of synchronization and thus often lead
to buggy / unnecessary code.  There are a couple legitimate use cases
in kernel.  Hopefully, they can be converted and
[delayed_]work_pending() can be removed completely.  Even if not,
removing most of misuses should make it more difficult to find
examples of misuses and thus slow down growth of them.

These changes are independent from other workqueue changes.

The changes are available in the following git branch
