Signed-off-by: Zorro Lang --- Hi, V2 did below changes: - "_fail" if scratch_mkfs/mount run fails - add _require_test_program "feature" - some code style change - "kill -0 $fsstress_pid 2>/dev/null" instead of "[ $(ps -ef | grep "fsstress" | grep -v -c grep) -gt 0 ]" - move the last unfreeze operation to _cleanup - increase fsstress' nops from 600 to 1000 Until now, it ran about 97s in my test x86_64 machine which has 8 cpus, 64G memory.
