exec will cancel any threads, including the ones that io-wq is using. This isn't a problem, in fact we'd prefer it to be that way since it means we know that any async work cancels naturally without having to handle it proactively. But it does mean that we need to setup a new manager, as the manager and workers are gone. Handle this at queue time, and cancel work if we fail. Since the manager can go away without us noticing, ensure that the manager itself holds a reference to the 'wq' as well. Rename io_wq_destroy() to io_wq_put() to reflect that. In the future we can now simplify exec cancelation handling, for now just leave it the same. Signed-off-by: Jens Axboe <axboe@kernel.dk> |

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.
