From: Bobi Jam <bobijam.xu@xxxxxxxxx>
'commit 77605e41a26f ("staging/lustre/clio: add pages into writeback cache
in batches")' adds a page to a list aggregate issuing them to writeback
cache; A page add is referenced in llite/vvp io scope, while writeback
cache commit de-refers it under osc sub io scope, and enabling -lu_ref
will detect this scope mismatch.
