I don't actually know. I just wondered, I had the vague impression
that the CRUSH from Ceph was copied into the kernel but I didn't know
who did it, if it was parallel development or a blanket copy or
what.
It /does/ mean that any changes to libcrush have to be kept as kernel
compatible C code, which isn't bad, it's just good to make sure it's
explicit.
