Re: [PATCH 4/4] ptrace: fix possible zombie leak on PTRACE_DETACH

ACK on the change, though looks different if you put __ptrace_detach in
ptrace.c with the earliar patch, as I suggest. Also, I think this warrants
a comment for the release_task call mentioning briefly what it means:

/*
* The flag means __ptrace_detach() determined that this child
* was a zombie that should have been auto-reaped already.
* Don't leak it.
*/
if (unlikely(dead))
release_task(child);


Thanks,
Roland
