We run all XDomain requests during discovery in tb->wq and since it only runs one work at the time it means that sending back reply to the other domain may be delayed too much depending whether there is an active XDomain discovery request running. To make sure we can send reply to the other domain as soon as possible run tb_xdp_handle_request() in system workqueue instead. Since the device can be hot-removed in the middle we need to make sure the domain structure is still around when the function is run so increase reference count before we schedule the reply work.

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.
