When the taks that submitted a request is dying, a task work for that request might get run by a kernel thread or even worse by a half dismantled task. We can't just cancel the task work without running the callback as the cmd might need to do some clean up, so pass a flag instead. If set, it's not safe to access any task resources and the callback is expected to cancel the cmd ASAP.

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 reStructuredText 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.
