I know, I mean any array that is created or assembled in new kernels will now have
lsb field stored in metadata. This field is not defined in old kernels and that's why
array can't assembled in old kernels, due to unknown metadata.

This is what we have to do for new features, and we're planning to avoid the forward
compatibility issue with the above patch that I mentioned.
