Hmm, I guess we need to agree on which tree takes mempool patches, then
we can just rebase one side.

I also find 25c4d8d29dbb odd.  Yes, with PREEMPT_RT anything taking
spinlocks could sleep in the normal sense, but pretty much everything
in Linux assumes spinlocks as spinning.  So if we want to update that
we should agree on global conventions for it and not starting to update
random little functions individually.
