From 3c7714485dc8adc810b6c52058992cfc767dfcb5 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Tue, 19 Feb 2019 00:04:58 +0000 Subject: [PATCH 1/1] pack-bitmap: switch hash tables to use struct object_id Instead of storing unsigned char pointers in the hash tables, switch to storing instances of struct object_id. Update several internal functions and one external function to take pointers to struct object_id.
