Hello Baoquan,

You are right, this patch actually only renamed mm/swap.c to mm/folio_lru.c,
I'll update it, The swap-specific was moved out in the preceding
patch, forgetting
to update it when split patch.

This sentence is outdated, I'll remove it, the sysctl defaults are
spread across many mm/*.c files.
I'll also fix the stale file header comment in folio_lru.c and check
other files.

Thanks,
