As checkpoint=merge comes in, mount option setting related to
checkpoint had been mixed up. Fixed it.

What if: -o checkpoint=merge,checkpoint=enable
Can you please explain the rule of merge/disable/enable combination and their
result? e.g.
checkpoint=merge,checkpoint=enable
checkpoint=enable,checkpoint=merge
checkpoint=merge,checkpoint=disable
checkpoint=disable,checkpoint=merge
If the rule/result is clear, it should be documented.
Thanks,
