+Subject: [PATCH] rt-tests: Add missing option F to optstring
+
+The cyclictest help output lists -F as the short version of the
+--fifo option, yet calling cyclictest -F produces an error
+cyclictest: invalid option --'F'".
+followed by the usage() message
+
+This patch adds -F as a valid argument.
