类型参数名称
struct inode *inode
1584  如果IS_NOQUOTA(inode)则返回
1594  dquots等于i_dquot(inode)
1595  以cnt小于MAXQUOTAS循环
1596  如果dquots[cnt]则退出
1600  如果cnt小于MAXQUOTAS则Release all quotas referenced by inode.* This function only be called on inode free or converting* a file to quota file, no other users for the i_dquot in* both cases, so we needn't call synchronize_srcu() after* clearing i_dquot.
