Applied, thank you Kees.
Eek! No, this will break the build: struct_group() is not yet in the tree. I can carry this with an Ack, etc.
I was pretty sure I saw struct_group() already in linux-next, but that was apparently a vacation-induced brainfart, sorry. Dropping.
Oh, for these two patches, can I add your Acked-by while I carry them?
Yes, thanks, and sorry for the noise.
