函数名称:qtree_read_dquot
函数原型:int qtree_read_dquot(struct qtree_mem_dqinfo *info, struct dquot *dquot)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct qtree_mem_dqinfo * | info | |
struct dquot * | dquot |
609 | sb等于 superblock this applies to |
612 | ret等于0 |
616 | 如果非 inodes of quotafiles [type]则 |
617 | quota_error(sb, "Quota invalidated while reading!") |
618 | 返回:负EIO |
624 | 如果offset小于等于0则 |
625 | 如果offset小于0则quota_error(sb, "Can't read quota structure for id %u", from_kqid( & userns count is 1 for root user, 1 for init_uts_ns,* and 1 for... ?, ID this applies to (uid, gid, projid) )) |
631 | 设置内存位 |
632 | memset( & Diskquota usage [dq_dqb_lock] , 0, sizeof(structmem_dqblk)) |
634 | 转到:out |
641 | ret等于quota_read(sb, type, ddquot, Size of quota entry in quota file , Offset of dquot on disk [dq_lock, stable once set] ) |
643 | 如果ret不等于Size of quota entry in quota file 则 |
646 | quota_error(sb, "Error while reading quota structure for id %u", from_kqid( & userns count is 1 for root user, 1 for init_uts_ns,* and 1 for... ?, ID this applies to (uid, gid, projid) )) |
648 | 设置内存位 |
649 | memset( & Diskquota usage [dq_dqb_lock] , 0, sizeof(structmem_dqblk)) |
650 | 释放内存 |
651 | 转到:out |
653 | 加自旋锁 |
654 | disk2mem_dqblk(dquot, ddquot) |
655 | 如果非absolute limit on disk blks alloc 且非preferred limit on disk blks 且非absolute limit on allocated inodes 且非preferred inode limit 则设置内存位 |
660 | 自旋锁解锁 |
661 | 释放内存 |
662 | out : |
663 | dqstats_inc(DQST_READS) |
664 | 返回:ret |
