Hi all,

File folio supports any order and multi-size THP is upstreamed[1], so both
file and anonymous folios can be >0 order. Currently, split_huge_page()
only splits a huge page to order-0 pages, but splitting to orders higher than
0 is going to better utilize large folios. In addition, Large Block
Sizes in XFS support would benefit from it[2]. This patchset adds support for
splitting a large folio to any lower order folios and uses it during file
folio truncate operations.

For Patch 6, Hugh did not like my approach to minimize the number of
folios for truncate[3]. I would like to get more feedback, especially
from FS people, on it to decide whether to keep it or not.

I'm curious, would it make sense to exclude the "more" controversial parts (i.e., patch #6) for now, and focus on the XFS use case only?
