The planned shared nr_active handling for unbound workqueues will make pwq_dec_nr_active() sometimes drop the pool lock temporarily to acquire other pool locks, which is necessary as retirement of an nr_active count from one pool may need kick off an inactive work item in another pool. This patch moves pwq_dec_nr_in_flight() call in try_to_grab_pending() to the end of work item handling so that work item state changes stay atomic. process_one_work() which is the other user of pwq_dec_nr_in_flight() already calls it at the end of work item handling. Comments are added to both call sites and pwq_dec_nr_in_flight(). This shouldn't cause any behavior 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.
