btrfs-progs: inspect: use btrfs_open_dir for btrfs inspect 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 inspect-internal rootid /mnt/tmp1 ERROR: Failed to lookup root id - Inappropriate ioctl for device btrfs inspect-internal rootid: rootid failed with ret=-1 # ./btrfs inspect-internal inode-resolve 256 /mnt/tmp1 ioctl ret=-1, error: Inappropriate ioctl for device # ./btrfs inspect-internal min-dev-size /mnt/tmp1 Error invoking tree search ioctl: Inappropriate ioctl for device After patch: # ./btrfs inspect-internal rootid /mnt/tmp1 ERROR: not a btrfs filesystem: /mnt/tmp1 # ./btrfs inspect-internal inode-resolve 256 /mnt/tmp1 ERROR: not a btrfs filesystem: /mnt/tmp1 # ./btrfs inspect-internal min-dev-size /mnt/tmp1 ERROR: not a btrfs filesystem: /mnt/tmp1 Signed-off-by: Zhao Lei <zhaolei@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>
