Inline io_task_work_add() into io_req_task_work_add(). They both work with a request, so keeping them separate doesn't make things much more clear, but merging allows optimise it. Apart from small wins like not reading req->ctx or not calculating @notify in the hot path, i.e. with tctx->task_state set, it avoids doing wake_up_process() for every single add, but only after actually done task_work_add().

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.
