Hi Zhongyi,

1) I think .needs_driver can parse either CONFIG_BLK_DEV_LOOP=y or 
CONFIG_BLK_DEV_LOOP=m correctly.
     Do you have any issue that .needs_driver cannot parse 
CONFIG_BLK_DEV_LOOP=y correctly?
2) If CONFIG_BLK_DEV_LOOP is not set, we would like to report TCONF by 
.needs_driver rather than TBROK by tst_find_free_loopdev().

Best Regards,
Xiao Yang
