Btrfs-progs: list all qgroups impact given path(exclude ancestral qgroups)
This patch introduces '-f' option which can help you filter the qgroups
by the path name, you may use it like:
btrfs qgroup show -f <path>
For example:
qgroupid(2/0)
/ \
/ \
qgroupid(1/0)
/ \
/ \
/ \
qgroupid(0/1) qgroupid(0/2)
sub1 sub2
/ \
/ \
dir1 file1
If we use the command:
btrfs qgroup show -f sub1/dir1
The result will output
0/1 -- --
'-f' option helps you list all qgroups impact given path.
(exclude ancestral qgroups)
