+Subject: [PATCH] tests: mark performance-related tests as expensive
+
+These performance-related tests are slightly failure prone due to
+varying system load during the two runs.
+Marking these tests as "expensive" makes it so they are no longer run
+via "make check". You can still run them via make "check-expensive".
+This makes them less likely to be run by regular users.
+* tests/long-pattern-perf: Use expensive_.
+* tests/mb-non-UTF8-performance: Likewise.
+Reported by Jaroslav Skarvada in http://debbugs.gnu.org/21826
+and by Andreas Schwab in http://debbugs.gnu.org/21812.
