My main concern was -
A fixes tag means it might get auto backported to stable kernels too,

Not in the MM world -- IIRC. I think there is the agreement, that we 
decide what should go into stable and what not.

Andrew can correct me if my memory is wrong.

Yes, -stable maintainers have been asked to only backport patches where
the MM developers asked for that, with cc:stable.  There may be
slipups, but as far as I know this is working.

I don't actually know how they determine which patches need this
special treatment.  Pathname?  Signed-off-by:akpm?

I guess it is pathname, based on ignore_list file [1] of stable-queue repo.

Oh, that's a bit sad.

- other trees sometimes mess with mm/ and they probably aren't aware
  that they need an explicit cc:stable.

- misses drivers/block/zram and probably various other things that
  the MM team maintains.

Oh well, I guess simple mm/* coverage is good enough.  But I do worry a
little that useful fixes coming into mm/ via other trees without
cc:stable will get missed.
