btrfs-progs: quota: use btrfs_open_dir for btrfs quota 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 quota enable /mnt/tmp1
ERROR: quota command failed: Inappropriate ioctl for device
# ./btrfs quota disable /mnt/tmp1
ERROR: quota command failed: Inappropriate ioctl for device
# ./btrfs quota rescan /mnt/tmp1
ERROR: quota rescan failed: Inappropriate ioctl for device
#
After patch:
# ./btrfs quota enable /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs quota disable /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs quota rescan /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
