How about just using KM_ZERO on the allocation and doing something like
'if (oinfo) new->xbfi_oinfo = *oinfo'?
BTW, what's the use case for a zeroed out oinfo if we explicitly define
null/unknown owner types?

Any reason we don't set the owner here?

How about XFS_RMAP_OWN_AGFL? OWN_AG confuses me into thinking it's for
AG headers, but IIUC that is covered by OWN_FS.
