Good catch!

BTW at least ksm01 will fail on VM host with running VMs,
but that's another story not related to this patch.

mem.c:251: FAIL: pages_shared is not 1 but 3629.
mem.c:251: FAIL: pages_sharing is not 98302 but 113789.
mem.c:251: FAIL: pages_volatile is not 0 but 12.
mem.c:251: FAIL: pages_unshared is not 1 but 48519.

Kind regards,
Petr
