+commit cc927b9e22ebe6de1a6ed23ca8d14d1f3d790fb5
+Author: Petr Tesarik <petr@tesarici.cz>
+Date:   Fri Dec 27 12:17:35 2024 +0100
+
+    tests: Fix xlat-linux-x86_64-6.11-pti-user-ver with parallel runs
+    
+    The xlat-linux-x86_64-6.11-pti-user and xlat-linux-x86_64-6.11-pti-user-ver
+    test cases use the same input files, but the logic is flawed, because they
+    also use the same output file names. That fails if both run in parallel.
+    
+    Fixes: #85
+    Signed-off-by: Petr Tesarik <petr@tesarici.cz>
