Andrew, I'm about to trickle through the first six of probably fifteen patches, diffed against against top of next-20220301, equally applicable to mmotm 2022-02-28-14-45 (sorry, not looked at 2022-03-02-16-53 yet). These are independent patches, which may be applied or dropped as you wish: I'm not numbering them N/15, and I'm Cc'ing different interested parties on the different patches. More to come later today or tomorrow or after, I'm still updating commit messages and Cc-lists for the rebased and retested patches: many of which go back years, never quite reaching priority for posting until now. I'd hoped to send them earlier in the cycle, but mm/munlock took precedence - and the first I'll send is a fix to an issue there. Thanks, Hugh
