I think it is right.

If we format ext4 filesystem with quota feature, then the quota 
information will hidden in filesystem instead of visible file by using 
quotacheck.

But this feature needs mkfs > 1.43.0.

I guess we can remove do_mount by using SAFE_MOUNT like quotactl08 did.

But shouldn't it be used also in quotactl08, which
