Jens Axboe 0242f6426e io-wq: fix queue stalling race
We need to set the stalled bit early, before we drop the lock for adding
us to the stall hash queue. If not, then we can race with new work being
queued between adding us to the stall hash and io_worker_handle_work()
marking us stalled.

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.
