[PATCH 0/2] mm/huge_memory: Modularize and simplify folio splitting paths

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

This two-patch series focuses on refactoring the core logic of folio
splitting to improve code structure, clarity, and maintainability.

The first patch introduces a new consolidated helper function that groups
all the required tasks involved in a folio split. The second patch then
leverages this new helper to clearly separate the different execution
paths for uniform and non-uniform splitting, which simplifies
__split_unmapped_folio().

This series sets a better foundation for future optimizations and
maintenance in the huge memory handling code.

Also selftests/split_huge_page_test pass.

Wei Yang (2):
  mm/huge_memory: introduce __split_folio_and_update_stats() to
    consolidate split task
  mm/huge_memory: separate uniform/non uniform split logic in
    __split_unmapped_folio()
