From: Michal Hocko <mhocko@xxxxxxxx>
Subject: mm-oom-protect-costly-allocations-some-more-fix
Arnd has reported the following compilation warning:
mm/page_alloc.c: In function '__alloc_pages_nodemask':
mm/page_alloc.c:3651:6: error: 'compact_result' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This should be a false positive TRANSPARENT_HUGEPAGE depends on COMPACTION
so is_thp_gfp_mask shouldn't be true. GFP_TRANSHUGE is a bit tricky
and somebody might be using this accidently. Make sure that compact_result
is defined also for !CONFIG_COMPACT and set it to COMPACT_SKIPPED because
the compaction was really withdrawn.
