[PATCH] xfs/449: test xfs_info on a mounted block device

[Zorro Lang]

There was a bug, xfs_info fails on a mounted block device:

  # xfs_info /dev/mapper/testdev
  xfs_info: /dev/mapper/testdev contains a mounted filesystem

  fatal error -- couldn't initialize XFS library

  xfsprogs has fixed it by:

    bbb43745 xfs_info: use findmnt to handle mounted block devices
