Especially for the first patch which is necessary for the later fixes, since it introduces the lock we need. I'm going to spend a bit more time later this evening to see if I can sort it out. If not, we may have to live without the fixes on those trees.

I've applied the 2 missing changes to the 5.10.y tree.  The other ones
