btrfs-progs: qgroup: use btrfs_open_dir for btrfs qgroup command
We can use btrfs_open_dir() to check whether target dir is
in btrfs's mount point before open, instead of checking it in
kernel space of ioctl, and return fuzzy error message.
Before patch:
# ./btrfs qgroup create 1/5 /mnt/tmp1
ERROR: unable to create quota group: Inappropriate ioctl for device
#
# ./btrfs qgroup assign 1/5 2/5 /mnt/tmp1
ERROR: unable to assign quota group: Inappropriate ioctl for device
#
# ./btrfs qgroup show /mnt/tmp1
ERROR: can't perform the search - Inappropriate ioctl for device
ERROR: can't list qgroups: Inappropriate ioctl for device
#
# ./btrfs qgroup limit 1G 1/5 /mnt/tmp1
ERROR: unable to limit requested quota group: Inappropriate ioctl for device
After patch:
# ./btrfs qgroup create 1/5 /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs qgroup assign 1/5 2/5 /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs qgroup show /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs qgroup limit 1G 1/5 /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
