+Subject: [PATCH] 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>
