Yes, that's right.  When I say "applied", it means I applied it to my
local repository.  I am careful not to allude to the patch being
"pushed".  There is no guarantee when this will happen, since it
completly depends how busy the subsystem is.  For Backlight, as the
churn is low, the impetus for pushing is pretty low.

It has been "pushed" now though.

Thanks for letting me know.  I have now removed this tag.
