When can_swapin_thp() is unused, it prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y: mm/memory.c:4184:20: error: unused function 'can_swapin_thp' [-Werror,-Wunused-function] Fix this by removing the unused stub. See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static inline functions for W=1 build").
