In linux kernel since version 4.2 (release Date: 2015-08-30)  
Universal Flash Storage (UFS) is SCSI transport specification for
accessing flash storage on digital cameras, mobile phones and
consumer electronic devices.
A UFS controller communicates with a UFS device by exchanging
UFS Protocol Information Units (UPIUs).
UPIUs can not only be used as a transport layer for the SCSI protocol
but are also used by the UFS native command set.
This transport driver supports exchanging UFS protocol information units
with a UFS device. See also the ufshcd driver, which is a SCSI driver
that supports UFS devices.

Select this if you need a bsg device node for your UFS controller.
If unsure, say N.
