commit 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.
