From c49c82aa4c1036ba1629f73223cff53230e695f3 Mon Sep 17 00:00:00 2001 From: Abhishek Kumar Date: Wed, 17 Jun 2020 14:44:10 +0530 Subject: commit: move members graph_pos, generation to a slab We remove members `graph_pos` and `generation` from the struct commit. The default assignments in init_commit_node() are no longer valid, which is fine as the slab helpers return appropriate default values and the assignments are removed. We will replace existing use of commit->generation and commit->graph_pos by commit_graph_data_slab helpers using `contrib/coccinelle/commit.cocci'.
