Patch generated with --function-context for easier review. That makes
it look a lot bigger than it actually is, though.
The plugged leaks were added after v2.22.0 (2019-06-07) by the following
commits:
5c84b3396c 2019-06-18 commit-graph: load commit-graph chains
ef5b83f2cf 2019-06-12 commit-graph: extract fill_oids_from_packs()
8d84097f96 2019-06-18 commit-graph: expire commit-graph files
