[ Upstream commit 2978a505aa ]
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 ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
