Agreed...
Masami, it seems that (just in case, with or without "Turn trace_probe->files
into list_head" I sent) trace_kpobes needs the similar fix too? Plus it should
clear TP_FLAG_* if enable_k.*probe() fails.
Or enable_trace_probe() assumes that enable_kprobe() must succeed? In this
case probably WARN_ON(ret) makes sense.
