When quotas are enabled with the quotaon(8) command, it sets the MNT_QUOTA flag in the mount structure mnt_flag field. The mount structure holds a cached copy of the filesystem statfs structure in mnt_stat that includes a copy of the mnt_flag field in mnt_stat.f_flags. The mnt_stat structure may not be updated for hours. Since the mount command requests mount details using the MNT_NOWAIT option, it gets the mount's mnt_stat statfs structure whose f_flags field does not yet show the MNT_QUOTA flag being set in mnt_flag. The fix is to have quotaon(8) set the MNT_QUOTA flag in both mnt_flag and in mnt_stat.f_flags so that it will be immediately visible to callers of statfs(2).
