Some patch administrivia:

a) you were on the delivery path for this patch, so you should have
added your signed-off-by:. I have made that change to my copy.

There's no harm in also having a Reviewed-by:, but Signed-off-by:
does imply that, we hope.

b) Andrea's From: line appeared twice.

c) Please choose patch titles which identify the subsystem which is
being patched. Plain old "mm:" will suit, although "mm:
compaction:" or "mm/compaction" would be nicer.

For some weird reason people keep on sending me patches with titles like

drivers: mmc: host: omap.c: frob the nozzle

or similar. I think there might be some documentation file which
(mis)leads them to do this. I simply do the utterly obvious and
convert it to

drivers/mmc/host/omap.c: frob the nozzle


d) Please don't identify patches via bare commit IDs. Because
commits can have different IDs in different trees. Instead use the
form cf608ac19c95 ("mm: compaction: fix COMPACTPAGEFAILED
counting"). I end up having to do this operation multiple times a
day and it's dull. And sometimes I don't even have that commit ID
in any of my trees, because they were working against some other

Also note that the 40-character commit ID has been trimmed to 12
characters or so.
