The state TASK_UNINTERRUPTIBLE should be set just before schedule_timeout() call, so it knows the sleep mode it should enter. There is no point in setting TASK_UNINTERRUPTIBLE at the initialization of the thread as schedule_timeout() will set the state back to TASK_RUNNING. This fixes a warning in __might_sleep() call, as it's expecting the task to be in TASK_RUNNING state just before changing the state to a sleeping state.

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.
