From 14b6c32037b19a860132e4e37c09d2d9705ee500 Mon Sep 17 00:00:00 2001 From: Wang Shilong Date: Mon, 7 Oct 2013 15:21:39 +0800 Subject: 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 For Example: qgroupid(2/0) / \ / \ / \ qgroupid(1/0) qgroupid(1/1) \ / \ / qgroupid(0/1) If we use the command: btrfs qgroup show -c The result will output 0/1 -- -- -- 1/0 -- -- 0/1 1/1 -- -- 0/1 2/0 -- -- 1/0,1/1 Signed-off-by: Wang Shilong Signed-off-by: Miao Xie Signed-off-by: David Sterba Signed-off-by: Chris Mason --- cmds-qgroup.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'cmds-qgroup.c') diff --git a/cmds-qgroup.c b/cmds-qgroup.c index 96098c12..147bedc2 100644 --- a/cmds-qgroup.c +++ b/cmds-qgroup.c @@ -202,9 +202,10 @@ static int cmd_qgroup_destroy(int argc, char **argv) } static const char * const cmd_qgroup_show_usage[] = { - "btrfs qgroup show -p ", + "btrfs qgroup show -pc ", "Show all subvolume quota groups.", "-p print parent qgroup id", + "-c print child qgroup id", NULL }; @@ -219,7 +220,7 @@ static int cmd_qgroup_show(int argc, char **argv) optind = 1; while (1) { - c = getopt(argc, argv, "p"); + c = getopt(argc, argv, "pc"); if (c < 0) break; switch (c) { @@ -227,6 +228,10 @@ static int cmd_qgroup_show(int argc, char **argv) btrfs_qgroup_setup_print_column( BTRFS_QGROUP_PARENT); break; + case 'c': + btrfs_qgroup_setup_print_column( + BTRFS_QGROUP_CHILD); + break; default: usage(cmd_qgroup_show_usage); } -- cgit v1.2.3
