[PATCH 0/5] mm/huge_memory: cleanup __split_unmapped_folio()

[Wei Yang <richard.weiyang@gmail.com>]

This short patch series cleans up and optimizes the internal logic of folio
splitting, particularly focusing on the __split_unmapped_folio() function.

The goal is to improve clarity and efficiency by eliminating redundant
checks, caching stable attribute values, and simplifying the iteration
logic used for updating folio statistics.

These changes make the code easier to follow and maintain.

Wei Yang (5):
  mm/huge_memory: cache folio attribute in __split_unmapped_folio()
  mm/huge_memory: update folio stat after successful split
  mm/huge_memory: Optimize and simplify folio stat update after split
  mm/huge_memory: Optimize old_order derivation during folio splitting
  mm/huge_memory: Remove redundant split_order != new_order check in
    uniform_split
