      LU-9555 limited the data returned from statfs() (df) to the limits associated with a specific project quota if the directory has lli_projid set to a non-zero value.

      However, for consistency with ext4 and XFS (on which the project quota feature is based) this quota limit should only be imposed if the PROJINHERIT flag is set on the inode:

      static int ext4_statfs(struct dentry *dentry, struct kstatfs *buf)
{
        :
        :
#ifdef CONFIG_QUOTA
        if (ext4_test_inode_flag(dentry->d_inode, EXT4_INODE_PROJINHERIT) &&
            sb_has_quota_limits_enabled(sb, PRJQUOTA))
                ext4_statfs_project(sb, EXT4_I(dentry->d_inode)->i_projid, buf);
#endif
}

int xfs_fs_statfs(struct dentry *dentry, struct kstatfs *statp)
{
        :
        if ((ip->i_diflags & XFS_DIFLAG_PROJINHERIT) &&
            ((mp->m_qflags & (XFS_PQUOTA_ACCT|XFS_PQUOTA_ENFD))) ==
                              (XFS_PQUOTA_ACCT|XFS_PQUOTA_ENFD))
                xfs_qm_statvfs(ip, statp);
}
