Hi,
2007/6/6, Christoph Lameter <[email protected]>:
Note that the corruption seems to have its cause in a decrement done at
offset 16 into the object pointing to the refcount in struct hci_dev. So
it looks like the refcount was decremented after the object was freed.
sysfs related?
I tested several more times under 2.6.22-rc4, there's no such problem.
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.
Regards
dave
