Re: [PATCH v9 00/16] Sparse-index: integrate with status

>
> This is the first "payoff" series in the sparse-index work. It makes 'git
> status' very fast when a sparse-index is enabled on a repository with
> cone-mode sparse-checkout (and a small populated set).
>
> This is based on ds/sparse-index-protections AND mt/add-rm-sparse-checkout.
> The latter branch is needed because it changes the behavior of 'git add'
