[PATCH 0/1] sha1-file: split OBJECT_INFO_FOR_PREFETCH

I found this interaction while testing the VFS for Git fork rebasing onto v2.22.0-rc1 [1]. It seems this new flag meant for partial clone prefetches interacts poorly with the read-object hook we use in our fork.

The issue is that OBJECT_INFO_FOR_PREFETCH has multiple bits on, so testing "flag & OBJECT_INFO_FOR_PREFETCH" can be true even if not all bits are on. My fix simply splits the new bit into a special flag while keeping OBJECT_INFO_FOR_PREFETCH as a union of flags.

Jury is out if this fixes our problem, but it definitely seems like a bug waiting to happen in Git, too.

Thanks, -Stolee
