Subject: mm: move most file-based accounting to the node -fix
As noted by Johannes Weiner, NR_ZONE_WRITE_PENDING gets decremented twice
during migration instead of a dec(old) -> inc(new) cycle as intended.
This is a fix to mmotm patch
mm-move-most-file-based-accounting-to-the-node.patch
Note that it'll cause a conflict with
mm-vmstat-remove-zone-and-node-double-accounting-by-approximating-retries.patch
but that the resolution is trivial.
