Subject: [PATCH 0/1] midx: prevent writing a bitmap with zero objects

From: Taylor Blau <[email-masked]>

Here is a small patch I wrote after getting an alert that we tried to call
pack_pos_to_midx(..., 0) on a MIDX that contained zero objects.

The patch causes us to no longer write a bitmap for such a MIDX. More detailed
notes are within, and this is based on tb/midx-bitmap-corruption-fix. (The only
reason is that both this topic and that one add a new test to t5326, so merging
this one after that avoids a textual conflict).

Thanks in advance for your review.
