#                sg_unmap_example.txt
# This is an example of the contents of a file that can be given to sg_unmap
# For example, assume the /dev/sdc is a scratch disk (e.g. one made by the
# scsi_debug kernel module) then:
#    sg_unmap --in=sg_unmap_example.txt /dev/sdc

0x12345677,1	# unmap LBA 0x12345677
0x12345678 2	# unmap LBA 0x12345678 and 0x12345679
0x12340000 3333	# unmap 3333 blocks starting at LBA 0x12340000

0X5a5a5a5a5a	0  # unmaps 0 blocks (i.e. does nothing)

a5a5a5h
7		# unmap 7 blocks starting at LBA 0xa5a5a5

# Note that there can be leading and trailing whitespace and whitespace
# (plus comma) can be a separator.
#
# Example invocation:
# $ sg_unmap --in=../examples/sg_unmap_example.txt -vv /dev/sdc
# open /dev/sg2 with flags=0x802
#     unmap cdb: 42 00 00 00 00 00 00 00 58 00
