Yes, that's correct. These two xlators are dependent. Initially it was two
different options to enable each xlators to enable ctime feature.
The consumer had to enable both xlators with two different commands to
enable ctime feature. So it was decided
to provide the same key "features.ctime" to enable both xlators internally
resulting in two entries in volume info.
