Currently io_steal_work() is disabled, and every linked request should go through task_work for initialisation. Do io_req_work_grab_env() just before io-wq punting and for the whole link, so any request reachable by io_steal_work() is prepared. This is also interesting for another reason -- it localises io_req_work_grab_env() into one place just before io-wq punting, helping to to better manage req->work lifetime and add some neat cleanup/optimisations later.

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.
