From 51276c1832d64d3b8f4dfc06c3ef21bf74f1916e Mon Sep 17 00:00:00 2001 From: Jerry Zhang Date: Mon, 24 Oct 2022 20:07:40 +0000 Subject: [PATCH] patch-id: use stable patch-id for rebases Git doesn't persist patch-ids during the rebase process, so there is no need to specifically invoke the unstable variant. Use the stable logic for all internal patch-id calculations to minimize the number of code paths and improve test coverage.
