The patch titled
Subject: include/linux/hugetlb.h: make hstate_is_gigantic() inline
has been removed from the -mm tree. Its filename was
mm-madvise-enable-softhard-offline-of-hugetlb-pages-at-pgd-level-fix.patch
This patch was dropped because it was folded into mm-madvise-enable-softhard-offline-of-hugetlb-pages-at-pgd-level.patch
------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: include/linux/hugetlb.h: make hstate_is_gigantic() inline
Ignoring the argument of both alloc_huge_page_node() and
hstate_is_gigantic() causes a harmless warning:
mm/memory-failure.c: In function 'new_page':
mm/memory-failure.c:1493:18: error: unused variable 'hstate' [-Werror=unused-variable]
Turning one into an inline function makes the compiler see that the
variable is not meant to be unused.
Fixes: d81a077951f8 ("mm/madvise: enable (soft|hard) offline of HugeTLB pages at PGD level")
Fixes: 39b80148ffd7 ("mm/follow_page_mask: add support for hugepage directory entry")
