[PATCH 0/5] mm/rmap: Refactor try_to_unmap_one

[Dev Jain <dev.jain@arm.com>]

In preparation for batching anonymous large folio unmapping to optimize it,
refactor try_to_unmap_one. This series refactors hugetlb, anon-lazyfree
and anon-swapbacked logic into their own functions, significantly
reducing the length of the huge try_to_unmap_one.
