Patch series "mm/huge_memory: drop dead split helper variants".

Two trivial cleanups in the folio split API, found while auditing the
split helpers for the inode UAF fix [1]:

 - can_split_folio() is dead: only the !THP stub remains, no definition
   under CONFIG_TRANSPARENT_HUGEPAGE and no callers. Leftover from an
   earlier cleanup.

 - split_folio_to_list_to_order() has no direct callers; its only user
   is split_folio_to_order(), which always passes a NULL list. Fold it.

No functional change.


This patch (of 2):

can_split_folio() has no callers and no definition under
CONFIG_TRANSPARENT_HUGEPAGE; only the !THP stub remains, left behind by an
earlier cleanup.  Remove it.

No functional change.
