From e8277b3b52240ec1caad8e6df278863e4bf42eac Mon Sep 17 00:00:00 2001 From: Konstantin Khlebnikov Date: Thu, 18 Apr 2019 17:50:20 -0700 Subject: [PATCH] mm/vmstat.c: fix /proc/vmstat format for CONFIG_DEBUG_TLBFLUSH=y CONFIG_SMP=n Commit 58bc4c34d249 ("mm/vmstat.c: skip NR_TLB_REMOTE_FLUSH* properly") depends on skipping vmstat entries with empty name introduced in 7aaf77272358 ("mm: don't show nr_indirectly_reclaimable in /proc/vmstat") but reverted in b29940c1abd7 ("mm: rename and change semantics of nr_indirectly_reclaimable_bytes"). So skipping no longer works and /proc/vmstat has misformatted lines " 0". This patch simply shows debug counters "nr_tlb_remote_*" for UP.
