 [<ffffffff80038e33>] put_files_struct+0x6c/0xc3
 [<ffffffff8001543d>] do_exit+0x2d2/0x8b1
 [<ffffffff80047932>] cpuset_exit+0x0/0x6c

I'm confused - which end of ths stack is up?

cpuset_exit doesn't call do_exit, rather it's the other
way around.  But put_files_struct doesn't call do_exit,
rather do_exit calls __exit_files calls put_files_struct.
