too late :-) These bits were written 1.5 months ago and are already upstream:
3945dab: tracing, Text Edit Lock - SMP alternatives support 4460fda: tracing, Text Edit Lock - kprobes architecture independent support 0e39ac4: tracing, Text Edit Lock - Architecture Independent Code
I suspect ksplice could make use of text_mutex?
