Nicholas Mc Guire 11e13696a0 sched/completions/Documentation: Add recommendation for dynamic and ONSTACK completions
To prevent dynamic completion objects from being de-allocated while still
in use, add a recommendation to embed them in long lived data structures.

Also add a note for the on-stack case that emphasizes the dangers of
the limited scope, and recommends dynamic allocation if scope limitations
are not clearly understood.

[ mingo: Minor touch-ups of the text, expanded it a bit to make the
         warnings Nicholas added more prominent. ]

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.
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.
