Re: linux-3.7.1: kmemleak reports in comm "usb-storage"?

Hi,
  so I rebooted and retried. I reproduced the memleak which got reported after
unplugging a USB drive (the final attempt). About 3-4 times I plugged a drive
in and out. On the last round, I was either too fast to re-plugged the drive
or kernel is at fault, I got:

I reconnected after 8 seconds after the drive was plugged in recently (see the above timestamps).

Damn, not the xhci stacktrace as before although I have also hit this previously. Let's aquash at leats this bug.
Is it a related to the USB drive?


Disappointed with the i801 above ;-), I re-plugged the drive:
