The patch titled
Subject: mm, vmstat: remove zone and node double accounting by approximating retries -fix
has been removed from the -mm tree. Its filename was
mm-vmstat-remove-zone-and-node-double-accounting-by-approximating-retries-fix.patch
This patch was dropped because it was folded into mm-vmstat-remove-zone-and-node-double-accounting-by-approximating-retries.patch

Subject: mm, vmstat: remove zone and node double accounting by approximating retries -fix
As pointed out by Vlastimil, the atomic_add() functions are already
assumed to be able to handle negative numbers. The atomic_sub handling
was wrong anyway but this patch fixes it unconditionally.
This is a fix to the mmotm patch
mm-vmstat-remove-zone-and-node-double-accounting-by-approximating-retries.patch
