Hello.
Kill ptrace_{get,put}_breakpoints and task_struct->ptrace_bp_refcnt,
9899d11f "ptrace: ensure arch_ptrace/ptrace_request can never race
with SIGKILL" made this all unneeded.
Benjamin, Paul, arch_dup_task_struct()->flush_ptrace_hw_breakpoint(src)
on powerpc looks "obviously wrong". Don't we need
- flush_ptrace_hw_breakpoint(src);
+ dst->thread->ptrace_bps[0] = NULL;
?
Oleg.
