We have a handful of topics related to refs subsystem in flight,
and I am a bit lost here.

(1) kn/reflog-migration-fix (the above) was done as a "fix" for the
    issue reported by brian in
    https://lore.kernel.org/all/Z4UbkcmJAU1MT-Rs@tapette.crustytoothpaste.net/ 

(2) You mention that (1) is broken in the message I am responding
    to.  There is no known fix yet, so (1) needs to wait in 'next'
    until it gets fixed.

(3) kn/reflog-migration-fix-followup is a code clean-up for (1); it
    has to wait for (2) as well.

(4) kn/reflog-symref-fix is a fix for a different bug the commit
    that introduced the bug (1) addresses.  It can proceed
    independently from the other topics.

(5) ps/reflog-migration-with-logall-fix is another fix for a
   different bug introduced by the same series whose bugs are
   addressed by (1) and (4).  It can proceed independently from the
   other topics.

The above is my current understanding; did I miss any other relevant
topics that are related to these efforts, and/or did I misunderstand
the dependencies among them?

If I am not misunderstanding the current status of these topics,
I'll be marking (4) and (5) for 'next'; I am undecided for (3).

Thanks.
