+Subject: [PATCH] journal: Make sd_journal_previous/next() return 0 at
+ HEAD/TAIL
+
+Currently, both these functions don't return 0 if we're at HEAD/TAIL
+and move in the corresponding direction. Let's fix that.
+
+Replaces #23480
+
+Upstream-Status: Backport [https://github.com/systemd/systemd/commit/977ad21b5b8f6323515297bd8995dcaaca0905df]
