Side note w/o consequence for your patch: usb-storage is not a block-based device driver. It is a SCSI low-level provider which happens to need symbols from the block layer to adjust parameters of the SCSI request queue since there are no fitting abstractions supplied by the SCSI mid-level. -- Stefan Richter -=====-=-==- =--- ==--- http://arcgraph.de/sr/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
