We currently access current->comm directly. As we have

I'm not 100% convinced prctl(PR_SET_NAME) may be called at the time of
core dump, but the locking won't hurt. Note that siglock is not held in
format_corename.

John Stultz is working on some patches to convert get_task_common()
to printk %ptc, you will not need to worry about the locking issue.

Thanks.
