Subject: Re: VM_BUG_ON_PAGE(page_to_pgoff(page) != offset) on s390

Adding a note to update this thread: the v5.9 tree now has
033b5d775511 ("mm/khugepaged: fix filemap page_to_pgoff(page) != offset")
which fixes this VM_BUG_ON_PAGE (or data corruption) when CONFIG_NUMA
is not set: we are hoping that may have have been the problem here.
