A subject (and this includes normal net etiquette as well) should be a short description of what the email (or patch) is about, preferably under 80 characters. What you supplied is an abstract.
it should have been something as simple as:
ftrace: Don't disable interrupts when taking read_lock() for graph tracer
And don't rely on checkpatch.pl. Read Documentation/SubmittingPatches in the kernel proper.
