The test scripts can be found here:
https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/tree/setup/disk https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/tree/setup/fs https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/tree/tests/aim7
Here are the real commands they executed in this test:
modprobe -r brd modprobe brd rd_nr=1 rd_size=50331648 part_show=1
dmsetup remove_all wipefs -a --force /dev/ram0
mkfs -t xfs /dev/ram0 mkdir -p /fs/ram0 mount -t xfs -o nobarrier,inode64 /dev/ram0 /fs/ram0
for file in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor do echo performance > $file done
echo "500 32000 128 512" > /proc/sys/kernel/sem
cat > workfile <<EOF FILESIZE: 1M POOLSIZE: 10M 10 disk_wrt EOF
echo "/fs/ram0" > config
( echo ivb44 echo disk_wrt
