please note if this would need to be backported too.

why change the variable name, `toRecover` was still OK? Or at least I do not see
any improvement in making it easier to understand with `totalRecovery` if byte vs.
objects where a issue of confusion why not addressing that by using `toRecoverObjects`
or the like

Also, why not adding those metrics up? If, misplaced and unfound do not have any
overlap, IIRC, so would def. make sense for those - for degraded I'm not so sure
about overlap with the other two from top of my head though.
