* btrfs-progs: Schedule quota rescan if qgroup assign caused inconsistence.Qu Wenruo2015-08-31
| | | | | | | | | | | | | | | | | | NOTE: This patch needs to cooperate with kernel patches, which will fix a kernel bug that never clear INCONSISTENT bit and return 1 if quota assign makes qgroup data inconsistent. Some qgroup assign will cause qgroup data inconsistent, like remove a qgroup with shared extents from a parent qgroup. But some won't, like assign a empty(OK, nodesize rfer and exel) to a qgroup. Newer kernel will return 1 if qgroup data inconsistent and in that case we should schedule a quota rescan. This patch will do this in btrfs-progs.

| | | | | | | | | | | | | | | | | | | | | | | You might want to list qgroups in order of some items, such as 'qgroupid', 'rfer' and so on, you can use '--sort'. Now you can sort the qgroups by 'qgroupid', 'rfer','excl','max_rfer' and 'max_excl'. For example: If you want to list qgroups in order of 'qgroupid'. You can use the option like that: btrfs qgroup show --sort=+/-qgroupid <path> Here, '+' means the result is sorted by ascending order. '-' is by descending order. If you don't specify either '+' nor '-', the result is sorted by default - ascending order.

In order to improve the scalability of show_qgroups(), i add some important structures: struct qgroup_lookup { struct rb_root root; } /* *store qgroup's information */ struct btrfs_qgroup { struct rb_node rb_node; u64 qgroupid; u64 generation; u64 rfer; u64 rfer_cmpr; u64 excl_cmpr; u64 flags; u64 max_rfer; u64 max_excl; u64 rsv_rfer; u64 rsv_excl; struct list_head qgroups; struct list_head members; } /* *glue structure to represent the relations *between qgroups */ struct btrfs_qgroup_list { struct list_head next_qgroups; struct list_head next_member; struct btrfs_qgroup *qgroup; struct btrfs_qgroup *member; } The above 3 structures are used to manage all the information of qgroups. struct { char *name; char *column_name; int need_print; } btrfs_qgroup_columns[] We define a arrary to manage all the columns that can be outputed, and use a member variant(->need_print) to control the output of the relative column. Some columns are outputed by default. But we can change it according to the requirement of the users. For example: if outputing max referenced size of qgroup is needed,the function 'btrfs_qgroup_setup_column()' will be called, and the parameter 'BTRFS_QGROUP_MAX_RFER' (extend in the future) will be passsed to the function. After the function is done, when showing qgroups, max referenced size of qgroup will be output.
