[PATCH -tip 0/6] kprobes: treewide: Clean up kprobe code

Hi Ingo,

Here is a series of patches to cleanup the kprobes code. I tried to fix
error message issues, comments, checkpatch.pl issues and so on. Some
of those are what you suggested and pointed in the x86 stacktrace series.

https://lore.kernel.org/bpf/YOK39GTuueIDeaJL@gmail.com/

I decided to split this seires from the x86 stacktrace fix series because
there still be some on going discussions on that thread. The stacktrace
fix series will be rebased on this series (and I've almost done, except
for some discussion items).

Since this is a cleanup series, this does not change any functionality
(of course some error messages, warnings, lock assertions are chaneged)
but the coding styles are improved. I will continue this cleanup activities
for each architecture port, and rethink the internal coding design and
interfaces too.

Thank you,

---
