How about moving the function (as is) to mm/huge_memory.c, rename it to
get_hugepage_unmapped_area(), which is defined to NULL in huge_mm.h
when TRANSPARENT_HUGEPAGE is unset?
Great idea. Perhaps it should look something like this?
unsigned long thp_get_unmapped_area(struct file *filp, unsigned long addr,
unsigned long len, unsigned long pgoff, unsigned long flags)
{
Might want to keep the future possibility of PUD_SIZE THP in mind?
Yes, this is why the func name does not say 'pmd'. It can be extended to
support
PUD_SIZE in future.
Thanks,
