It's running stress test with tool like "fio --name=randrw_stress_round_1 --ioengine=libaio --direct=1 --time_based=1 --end_fsync=1 --ramp_time=5 --norandommap=1 --randrepeat=0 --group_reporting=1 --numjobs=4 --iodepth=128 --rw=randrw --overwrite=1 --runtime=36000 --bssplit=4K/44:8K/1:12K/1:16K/1:24K/1:28K/1:32K/1:40K/32:64K/5:68K/7:72K/3:76K/3 --filename=/dev/mmcblk0" The tool(application) is owned by user or with some standard tool.
