Subject: [PATCH 0/9] Btrfs: qgroup: part-1: bug fixes for qgroup inherit.
Date: Tue, 10 Feb 2015 18:23:12 +0800 [thread overview]
Message-ID: <1423563803-8996-1-git-send-email-yangds.fnst@cn.fujitsu.com> (raw)
Hi all,
[1/9] is a RESEND with a reviewed-by.
[2/9]-[6/9] are bug fixes about qgroup_inherit(), these patch make
user can set the limits when creating a subvolume with the related
patch in userspace applied.
[7/9]-[8/9] are a cleanup for qgroup.
[9/9] provides a way for btrfs-progs to get the quota status by ioctl(),
then btrfs-progs can warn user when they are using qgroup with quota_disabled.
With this series patch applied, both btrfs and btrfs-progs:
[root@atest-guest linux_btrfs]# btrfs quota enable /mnt
[root@atest-guest linux_btrfs]# btrfs qgroup show -prce /mnt
qgroupid rfer excl max_rfer max_excl parent child
-------- ---- ---- -------- -------- ------ -----
0/5 16.00KiB 16.00KiB 0.00B 0.00B --- ---
[root@atest-guest linux_btrfs]# btrfs sub create /mnt/sub1
Create subvolume '/mnt/sub1'
[root@atest-guest linux_btrfs]# btrfs qgroup show -prce /mnt
qgroupid rfer excl max_rfer max_excl parent child
-------- ---- ---- -------- -------- ------ -----
0/5 16.00KiB 16.00KiB 0.00B 0.00B --- ---
0/257 16.00KiB 16.00KiB 0.00B 0.00B --- ---
[root@atest-guest linux_btrfs]# btrfs sub create /mnt/sub2 -r 10M -e 5M
Create subvolume '/mnt/sub2'
Set qgroup arguments:
max reference: 10485760
max exclusive: 5242880
[root@atest-guest linux_btrfs]# btrfs qgroup show -prce /mnt
qgroupid rfer excl max_rfer max_excl parent child
-------- ---- ---- -------- -------- ------ -----
0/5 16.00KiB 16.00KiB 0.00B 0.00B --- ---
0/257 16.00KiB 16.00KiB 0.00B 0.00B --- ---
0/258 16.00KiB 16.00KiB 10.00MiB 5.00MiB --- ---
