Subject: mm/gup: move try_grab_page() to mm/internal.h
Date: Tue, 24 Jan 2023 16:34:25 -0400
This is part of the internal function of gup.c and is only non-static so
that the parts of gup.c in the huge_memory.c and hugetlb.c can call it.
Put it in internal.h beside the similarly purposed try_grab_folio()
