Why XFS is failing to mount with "nobarrier" mount option ?

Issue

• Mounting XFS filesystem fails with nobarrier option:

  # mount /dev/sdb1 -o nobarrier /mnt/data
  mount: /mnt: wrong fs type, bad option, bad superblock on /dev/vda1, missing codepage or helper program, or other error.
  

• /var/log/messages or dmesg shows the following message:

  [36080.303252] XFS (dm-2): unknown mount option [nobarrier].
  

• The root file system is mounted read-only, and the system cannot work fine after adding nobarrier option.

• The system cannot boot, and drops to emergency mode after adding nobarrier option.
