Hi,
I have noticed that name_to_handle() system call is failing on UBIFS due to missing super_block.s_export_op. Is there a reason why this hasn’t been implemented on UBI?

As I know, this *struct export_operations* is used for nfsd. But
NFS is not supported with UBIFS. So I guess this is the reason
why super_block.s_export_op is missing.

This is correct. UBIFS is not exportable, so no handles for you. :-)
