Tejun Heo c35aea39d1 workqueue: Update lock debugging code
These changes are in preparation of BH workqueue which will execute work
items from BH context.

- Update lock and RCU depth checks in process_one_work() so that it
  remembers and checks against the starting depths and prints out the depth
  changes.

- Factor out lockdep annotations in the flush paths into
  touch_{wq|work}_lockdep_map(). The work->lockdep_map touching is moved
  from __flush_work() to its callee - start_flush_work(). This brings it
  closer to the wq counterpart and will allow testing the associated wq's
  flags which will be needed to support BH workqueues. This is not expected
  to cause any functional changes.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
