From: Zi Yan ziy@nvidia.com Order-1 folio is not supported because _deferred_list, which is used by partially mapped folios, is stored in subpage 2 and an order-1 folio only has subpage 0 and 1.
The LBS patches has the patch from Matthew which enables and allowed us to successfully test order 1. So this restriction could be dropped if that gets merged.
OK. But it only applies to file-backed folios IIUC. Anonymous folios still cannot be split to order-1.
