From 9a53583b77c35576f87b7e29cb109b46d29ad803 Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Wed, 15 Oct 2025 18:27:36 -0400 Subject: [PATCH] builtin/repack.c: avoid "the_hash_algo" in `write_oid()` In a similar spirit as the previous commit, avoid referring directly to "the_hash_algo" within builtin/repack.c::write_oid(). Unlike the previous commit, we are within a callback function, so must introduce a new struct to pass additional data through its "data" pointer.
