Btrfs-progs: introduces '-c' option to print the ID of the child qgroups
This patch introduces '-c' option to print the ID of the child qgroups.
You may use it like:
btrfs qgroup show -c <path>
For Example:
qgroupid(2/0)
/ \
/ \
/ \
qgroupid(1/0) qgroupid(1/1)
\ /
\ /
qgroupid(0/1)
If we use the command:
btrfs qgroup show -c <path>
The result will output
0/1 -- -- --
1/0 -- -- 0/1
1/1 -- -- 0/1
2/0 -- -- 1/0,1/1
