There are a few transitions going on in the VFS right now. One is that we're deprecating and removing ->writepage; all filesystems need to be converted to ->writepages. The other is that we're switching filesystems from using pages to folios so they can support large folios and we can shrink the size of memmap. This completely untested series updates ubifs to the current APIs. You might be able to improve things; for example, it's common for filesystems to batch up the results of the writepage call and submit them at the end of the writepages method. But that would be suitable for a later patchset.
