Now we just kill fdatasync_work process and wait nothing after the test, so a busy unmount failure may appear if the fdatasync syscall doesn't return in time. umount: /tmp/scratch: target is busy. mount: /tmp/scratch: /dev/sdb already mounted on /tmp/scratch. !!! failed to remount /dev/sdb on /tmp/scratch This patch waits the xfs_io fdatasync subprocess exit to make sure _check_scratch_fs success.
