From: Masami Hiramatsu (Google) <mhira...@kernel.org> Add a test case for probing on a symbol in a module without module name. When probing on a symbol in a module, ftrace accepts both the syntax that <MODNAME>:<SYMBOL> and <SYMBOL>. Current test case only checks the former syntax. This adds a test for the latter one.
