| H A D | hugetlb.c | d79d176a Tue Oct 13 18:56:14 CDT 2020 Baoquan He <bhe@redhat.com> mm/hugetlb.c: remove the unnecessary non_swap_entry()
If a swap entry tests positive for either is_[migration|hwpoison]_entry(),
then its swap_type() is among SWP_MIGRATION_READ, SWP_MIGRATION_WRITE and
SWP_HWPOISON. All these types >= MAX_SWAPFILES, exactly what is asserted
with non_swap_entry().
So the checking non_swap_entry() in is_hugetlb_entry_migration() and
is_hugetlb_entry_hwpoisoned() is redundant.
Let's remove it to optimize code.
