[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 commit7aaf772723("mm: don't show nr_indirectly_reclaimable in /proc/vmstat") Node 0, zone DMA per-node stats nr_inactive_anon 403 nr_active_anon 89123 nr_inactive_file 128887 nr_active_file 47377 nr_unevictable 2053 nr_slab_reclaimable 7510 nr_slab_unreclaimable 10775 nr_isolated_anon 0 nr_isolated_file 0 <...> nr_vmscan_write 0 nr_vmscan_immediate_reclaim 0 nr_dirtied 6022 nr_written 5985 74240 ^^^^^^^^^^ pages free 131656 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 b29940c1abd7 ("mm: rename and change semantics of nr_indirectly_reclaimable_bytes"), so there is no such a problem anymore.

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.
