In the new version of the patch, the flag is named USBDEVFS_URB_BULK_CONTINUATION and it should be set for every URB after the first in a multi-URB bulk transfer. (Of course, URB_SHORT_NOT_OK should remain set for every URB in a bulk_IN transfer.) In the updated patch this mechanism affects all bulk transfers, not just bulk-IN. So for example, if a transient hardware problem causes a bulk-OUT URB to fail, the remaining URBs in that transfer will automatically be cancelled. I will post the new patch shortly. The expectation is that it will get into the next merge window, so it will appear in 2.6.32.
