Provide a mechanism for higher levels to create BUI/BUD items, submit them to the log, and a stub function to deal with recovered BUI items. These parts will be connected to the rmapbt in a later patch. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
