+Subject: [PATCH 2/2] Regression in commit abe92e8010ab affecting MariaDB tests
+
+I have disovered a regression in commit abe92e8010ab ("Prefer idx_t,
+ptrdiff_t to lin") while I was running MariaDB tests. The regression is
+related to a diff file [1], where the patch fails to apply it with
+following error:
+
+  patch: **** '---' expected at line 2 of patch
+
+To illustrate the issue, I have attached a git patch containing a
+testcase with simplified reproducer.
