From: Jann Horn <jannh@xxxxxxxxxx>
Subject: mm/vmstat.c: fix outdated vmstat_text
7a9cdebdcc17 ("mm: get rid of vmacache_flush_all() entirely") removed the
VMACACHE_FULL_FLUSHES statistics, but didn't remove the corresponding
entry in vmstat_text. This causes an out-of-bounds access in
vmstat_show().
Luckily this only affects kernels with CONFIG_DEBUG_VM_VMACACHE=y, which
is probably very rare.
