4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Roman Gushchin <guro@xxxxxx> commit 7aaf7727235870f497eb928f728f7773d6df3b40 upstream. Don't show nr_indirectly_reclaimable in /proc/vmstat, because there is no need to export this vm counter to userspace, and some changes are expected in reclaimable object accounting, which can alter this counter.
