I don’t know, but that’s pre-existing.  (It doesn’t set .is_filter.)

I’m afraid I have little insight into what blkreplay actually does.  I
thought maybe in conjunction with the whole replay stuff it might turn
out not to be a filter.

So is it a filter?  If so, no problem.  I suppose we can fix it up in
the same patch that marks mirror-top and commit-top as filters.
