Thanks for your patch!

mm/huge_memory.c: In function ‘__split_huge_page’:
mm/huge_memory.c:2423:16: error: implicit declaration of function
‘swap_address_space’; did you mean ‘exit_swap_address_space’?
[-Werror=implicit-function-declaration]
 2423 |   swap_cache = swap_address_space(entry);
      |                ^~~~~~~~~~~~~~~~~~
      |                exit_swap_address_space

mm/huge_memory.c needs to #include "swap.h", too.

when I'm talking to journalists I just say "programmer" or something like that.
