Yes, exactly!

The second patch "ptrace: do not use task_lock() for attach" has nothing
to do with utrace, and it is really pure ptrace cleanup.

But it can't be applied to -mm tree, because it (textually) conficts with
utrace changes in ptrace_attach().

Yes, but in this case, how can we push it before utrace-core.patch ?

The first patch is only for -mm, to avoid the painful dependencies.


Since you seem to mostly agree with the second patch, what should I do?

Oleg.
