Deprecate this driver. All devices which can be handled by this driver
can also be handled by the usb-storage driver.

+What: Low Performance USB Block driver ("CONFIG_BLK_DEV_UB")
+When: 3.6
+Why: This driver provides support for USB storage devices like "USB
+ sticks". It translates the requests from the block layer into
+ READ & WRITE requests. It does not use the SCSI layer for device
+ handling and as results sdparm & smartmontool do not work. It
+ does not use libusual which holds various workarounds for
+ certain buggy devices.
+ As of now, it is deactivated in Debian, Fedora and Ubuntu. All
+ current users can switch over to usb-storage (CONFIG_USB_STORAGE)
+ which only drawback is the additional SCSI stack.
