David Howells ffb8fd39c8 watch_queue: Make comment about setting ->defunct more accurate
commit 4edc076041 upstream.

watch_queue_clear() has a comment stating that setting ->defunct to true
preventing new additions as well as preventing notifications.  Whilst
the latter is true, the first bit is superfluous since at the time this
function is called, the pipe cannot be accessed to add new event
sources.

Remove the "new additions" bit from the comment.

Fixes: c73be61ced ("pipe: Add general notification queue support")

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.
