  1825	Description:	This file provides an interface for host to send LBA ranges to
  1826			the device for UFS file-based optimization. First, we obtain the iNode
  1827			info of the file, which can be used to find out the corresponding block
  1828			address of the file, then add the offset of each partition to obtain the
  1829			LBA of the file. We can send LBA info to the device as a comma separated
  1830			string. Each adjacent pair represents a range:<open-lba>,<close-lba>.
  1831			e.g. The LBA range of the file is 0x1234,0x3456;0x4567,0x5678
  1832				echo 0x1234,0x3456,0x4567,0x5678 > fbo_send_lba
