    Yeah, that patch is how you ended up cc'ed - it was already in the linux-next
    patch in Andrew's -mmotm tarball. It looked like you addressed one corner case
    of the problem, and I tripped over another. But now I'm trying to get my
    brain wrapped around how I was able to get SQUASHFS_LZMA=y, and it had a
    select for DECOMPRESS_LZMA, but that *still* was 'n' anyhow? How did we end
    up with both && and || in that 'Selected by:' line? Is that saying that
    RD_LZMA needs to be on too?

    Adding some plausible-sounding kbuild-related entries from MAINTAINERS to
    the cc: list, maybe they can explain it...
