From 5f77ed8aa58917ae6d5fe8133ef734bc97ae3803 Mon Sep 17 00:00:00 2001 From: Daniel Gustafsson Date: Wed, 29 Jul 2026 13:33:00 +0200 Subject: [PATCH v3 2/2] Add a comment to distinguish backend types The data checksums entries were seemingly auxiliary processes from reading the code, but they are in fact background workers. Add a comment to clarify. Backpatch down to v19 where online checksums were added.
