#
# Test zonemode=strided. This uses the null ioengine when no file is
# specified. If a file is specified, use it for randdom read testing.
# Some of the zoneranges in the tests are 16MiB. So when using a file
# a minimum size of 32MiB is recommended.
#
# USAGE
# python strided.py fio-executable [-f file/device]
#
# EXAMPLES
# python t/strided.py ./fio
# python t/strided.py ./fio -f /dev/sda
# dd if=/dev/zero of=temp bs=1M count=32
# python t/strided.py ./fio -f temp
#
# REQUIREMENTS
# Python 2.6+
#
# ===TEST MATRIX===
#
# --zonemode=strided, zoneskip unset
#   w/ randommap and LFSR
#       zonesize=zonerange  all blocks in zonerange touched
