Yes.  The only nastiness is around drivers/ide - there it gets a bunch of
annoying conflicts from the ide-{disk,floppy}_ioctl.c splitoff.  Other than
that, it's trivially ported on top of current linux-next.  Merge order is
going to be interesting - depending on whether block merge happens before
or after ide one.

I'm going to put linux-next-based series on kernel.org tonight, before
going to Portland...
