Entering tctx_task_work() with empty task_list is a strange scenario, that can happen only on rare occasion during task exit, so let's not check for task_list emptiness in advance and do it do-while style. The code still correct for the empty case, just would do extra work about which we don't care. Do extra step and do the check before cond_resched(), so we don't resched if have nothing to execute.

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.
