Hmm, by any chance, was the USB disk pulled before the umount actually run?
Jens, it seems we have destroyed the BDI before the filesystem was properly
unmounted (the oops is just NULL pointer dereference hidden by new percpu code)
because fbc->counters == NULL for the BDI_RECLAIMABLE stats counter.
