However, scsi_debug does not support DAX capabilities. When xfstests is configured with DAX mount options, ext4 strictly validates the block device during the mount phase. This results in a mount failure: EXT4-fs (sdc): DAX unsupported by block device. Skip this test for ext4 when the 'dax' mount option is present to avoid false failures.
