I think these two can be merged independently of the radix tree change.
They seem ready to me and having them upstream will make it easier for new
KHO functionality, like e.g. "kexec history" patches 
(https://lore.kernel.org/all/20260102-kho-v2-0-1747b1a3a1d6@debian.org)

I'm going to prepare a series with these two patches and some few more
updates to KHO and LUO docs and I'll send them in the next few days.
