The selftest for ftrace checks some features by checking if the README has text that states the feature is supported by that kernel. Unfortunately, this check gives false positives because it many not be checked if there's spaces in the string to check. This is due to the compare between the required variable with the ":README" string stripped, because neither has quotes around them.
