Eric W. Biederman dd621ee0cf kthread: Warn about failed allocations for the init kthread 
Failed allocates are not expected when setting up the initial task and
it is not really possible to handle them either.  So I added a warning
to report if such an allocation failure ever happens.

Correct the sense of the warning so it warns when an allocation failure
happens not when the allocation succeeded.  Oops.

README 

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.
