[Patch v2 0/2] 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 
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.

The split_huge_page_test selftest pass.
