OK, so this missed the SCSI cutoff window because the series wasn't
finalised until 17 March and, originally, I thought Linus would cut us
off at -rc7 which was 16 March.  In reality we got an extra week, but I
spent that ironing out a few late arriving bugs in the tree itself
rather than integrating features.

For drivers, I'm willing to buck the release protocols a bit because
they're self contained, but for core features, they are supposed to be
all finalised by -rc5.  Plus Linus bites me every time I do it even for
drivers, so I was actually letting the scars heal a bit.

I also don't see this in linux-next, unless I'm not looking in the right
place, so it would be a bit of a risk adding it just before -rc1.
