 I ran the whole systemtap testsuite with a kernel built from your git
 tree, and did not see any utrace-specific issues.  Thanks!
I have got the git tree, too.
I can confirm that also my kmview works on this version of utrace.
Thank you Oleg.

[RFC v2 00/19] utrace for 3.0 kernel

2011-06-30 Thread Oleg Nesterov 
Another attempt. This version tries to decouple utrace and ptrace.
This way it is much simpler to follow the upstream changes, afaics.

TODO:

- The single-stepping updates in ptrace_resume() can race
  with utrace_reset()-user_disable_single_step().

  This was fixed by 20/20, but I noticed that this patch
  is buggy right before sending.

- Perhaps PTRACE_SYSEMU/TIF_SYSCALL_EMU logic was broken,
  I need to recheck.

- Testing.

Oleg.
