Chengming Zhou c5f51572a7 ftrace: Do not let direct or IPMODIFY ftrace_ops be added to module and set trampolines ... When inserting a module, we find all ftrace_ops referencing it on the ftrace_ops_list. But FTRACE_OPS_FL_DIRECT and FTRACE_OPS_FL_IPMODIFY flags are special, and should not be set automatically. So warn and skip ftrace_ops that have these two flags set and adding new code. Also check if only one ftrace_ops references the module, in which case we can use a trampoline as an optimization.
