I got a quick question about quota, Hi, typedef struct xfs_dquot { xfs_qcnt_t q_res_bcount; /* total regular nblks used+reserved */ }; while the generic quota used by ext4/ocfs2, struct mem_dqblk { qsize_t dqb_curspace; /* current used space */ qsize_t dqb_rsvspace; /* current reserved space for delalloc*/ }; and ext4 ->statfs() only displays dqb_curspace while xfs ->statfs() displays both, Q1: is it a ext4 bug? Q2: I didn't see the code where rsv_space is converted to used space, am I missing anything? thanks, liubo thanks, liubo
