NeilBrown 4db74c184a Fix termination state for idr_for_each_entry_ul()
[ Upstream commit e8ae8ad479 ]

The comment for idr_for_each_entry_ul() states

  after normal termination @entry is left with the value NULL

This is not correct in the case where UINT_MAX has an entry in the idr.
In that case @entry will be non-NULL after termination.
No current code depends on the documentation being correct, but to
save future code we should fix it.

Also fix idr_for_each_entry_continue_ul().  While this is not documented
as leaving @entry as NULL, the mellanox driver appears to depend on
it doing so.  So make that explicit in the documentation as well as in
the code.

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.
