Oh, I made the original uplift patch a year ago and confused with the below
patch at that time.
I missed this, when writing new patches based on the old ones recently.

https://lkml.org/lkml/2015/5/11/1214

I made that patch to resolve the changed page index by fcollapse.
But, simply I noticed that encryption doesn't support fcollapse or finsert.

Thanks,
