assuming that you are the one who will apply this patch: Note that it
depends on patch 1 that Takashi already applied to his tree. So you
either have to wait untils patch 1 appears in some tree that you merge
before applying, or you have to take patch 1, too. (With Takashi
optinally dropping it then.)

Best regards
Uwe
