See my other reply, are you sure we should make this change? From a
"keep the old behavior" POV maybe so, but this looks to me like a
bug in busybox, passing fstab hint "options" like "auto" as actual mount
options being the root cause of the problem. debugfs isn't uniquely
affected by this behavior.

I'm not dead set against the change, just wanted to point this out.

Thanks,
