Hi,
This patch adds a basic startup self-test for removing a traced function.
Being kallsyms_lookup_name made unexported there is no easy use of ftrace_set_filter_ip from kernel modules, leaving with ftrace_set_filter as the way to set trace functions. The ftrace_set_filter API is not explicit on how to remove trace functions, and there is no such use case either in the kernel source-tree for which I decided to add an example of it use as a self-test.
Changes since v1: - Added changelog and sign-off line.
