Oh, apparently I never pushed out yesterday. The patch literally just affects the (useless) hex number. So: cat /proc/self/stack now prints out [<0>] proc_pid_stack+0xaa/0x100 [<0>] proc_single_show+0x48/0x80 [<0>] seq_read+0xd2/0x410 ... instead of putting some randomized kernel address there. I considered getting rid of the whole "[<>]" thing, but that's where "maybe there are tools that parse this" came in. I doubt there are any, though. If proc-ps doesn't look at this, I don't know what could. But the format change might as well be a separate thing if somebody cares deeply. Linus
