no worries - just to clarify a bit more, the issue gets slightly
more complex :-) .

I.e. patches should always target the maintainer-branch you're expecting
them getting applied to. During the whole development cycle there is a
lot of movement happening in each maintainer tree, so targetting some
completely separate rc-kernel won't really make sense.

Most of the time targetting -rc1 might work in the beginning, but when
there are other changes already applied you need to take these into
account too.
