Hi Gerg,
Sorry, i may understand your confusion.
I thought 'Upstream' as the newest code, so, I said 'Upstream has no this bug'.
Yes, we found this bug on 'Upstream v4.19.191'.
How could i submit this patch to 'longterm: 4.19'.
Thanks.

Hi Greg,
Upstream replaces migrate_page_move_mapping() with
folio_migrate_mapping(),
does not use radix tree any more. So, the upstream don't have the null
pointer bug.
We found and fix this bug on '4.19.191'.
