> The XFS filesystem has gained the ability to use large folios in the page cache and some associated optimizations, all of which should improve performance significantly for some workloads

XFS has been using large folios in the page cache since May 2021 (merged into v5.17). What's changed here is the ability to create large folios for cached writes. Previously, large folios were only created by read() or mmap().

The patches from Ritesh aren't exactly associated. His motivation was random-write workloads with a block size < PAGE_SIZE, almost the exact opposite problem. It's purely scheduling that they ended up in the same git pull.
