Subject[RFC PATCH] set TASK_TRACED before arch_ptrace code to fix a race
Hello list,

The following patch is to fixed a race in ptrace_stop handling which
causes "strace" hang if the target process blocks SIGTRAP with the
test case filed at
Please note this is just IA64 problem because just IA64 has
arch_ptrace_stop_needed defined, and has arch_ptrace_stop defined that
would set notify_resume flags for syncing rbs...but it also opens the
door to invoke ia64_do_signal->get_signal_to_deliver before setting
current PTRACED flag. Please help review.

**The patch is enclosed in text attachment*
**I'm using web client to send the patch* *
