From this subthread with Linus, removal of the exofs fs and scsi osd
code would be a user visible change and is not an option. See:
https://lkml.org/lkml/2018/10/27/3
https://lkml.org/lkml/2018/10/27/44

So we should pursue this much smaller fixup.  Boaz, can you clarify
https://lkml.org/lkml/2018/10/26/682
specifically:
