This is already explained in detail in the patch 'commit-graph: add
large-filters bitmap chunk', although there is an error in the quoted
part of your email (which I wrote) which refers the reader to the
previous patch. The patch I'm actually referring two is the
twice-previous patch.

I'll fix that locally before re-sending.

Thanks,
Taylor
