I didn't pay much attention to the early patches when they flew past a couple of months ago and there's been basically no email about it since (unless it's on some other list?) Changelogs don't seem to explain it much and it seems to be undocumented. It's nicely commented, but it would be useful to at least present the kernel<->userspace API in a way which can be reviewed. You'd think that uninlining ftrace_ip_in_hash() would save a few bytes, but it saves zero. Even noinline doesn't change it. Weird. hm, gcc has gone and ignored the `inline'. heh.
