Roman Gushchin d49dea545a mm: hide incomplete nr_indirectly_reclaimable in /proc/zoneinfo 
[fixed differently upstream, this is a work-around to resolve it for 4.19.y]

Yongqin reported that /proc/zoneinfo format is broken in 4.14
due to commit 7aaf772723 ("mm: don't show nr_indirectly_reclaimable
in /proc/vmstat")

The problem is caused by the nr_indirectly_reclaimable counter,
which is hidden from the /proc/vmstat, but not from the
/proc/zoneinfo. Let's fix this inconsistency and hide the
counter from /proc/zoneinfo exactly as from /proc/vmstat.

BTW, in 4.19+ the counter has been renamed and exported by
the commit b29940c1ab ("mm: rename and change semantics of
nr_indirectly_reclaimable_bytes"), so there is no such a problem
anymore.

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.
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.
