The hci_dev_put is indeed a bug, isn't it? it decrement the refcout on more time like you said. But why the slub doesn't warning under 2.6.22-rc4 but do under 2.6.22-rc3-mm1? I'm puzzled. And if this is a bug , should I write another post to list? then to mm or mainline? I'm still new to kernel list, thanks you all.
