Well the embedded folks are crazy. They argue for weeks about 10 bytes. It is 125KiB for scsi module and 25KiB for sd on only 14KiB for ub on my i386. By deactivating the verbose thingy the scsi module goes down to 87KiB. So we talk here about 100KiB in best case 136KiB in worst case. After a grep on the defconfig we have - CONFIG_BLK_DEV_UB=m + CONFIG_USB_STORAGE=m in * arch/arm/configs/s3c2410_defconfig * arch/mips/configs/rm200_defconfig * arch/powerpc/configs/pmac32_defconfig - CONFIG_BLK_DEV_UB=y * arch/mips/configs/db1200_defconfig * arch/mips/configs/db1300_defconfig * arch/mips/configs/pb1100_defconfig * arch/mips/configs/pb1500_defconfig * arch/mips/configs/pb1550_defconfig So the former three have activated both so they hardly care about size :). The 5 alchemy board look kinda odd. My best guess is that it was activated the db1200 and the other got it via copy. So let me prepare a patch for a removal as you suggested. > >-- Pete Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
