[PATCH] mm/hugetlb: suppress wrong warning info when alloc gigantic page

From: Chen Wandun
Date: Fri Feb 19 2021 - 07:32:05 EST


If hugetlb_cma is enabled, it will skip boot time allocation
when allocating gigantic page, that doesn't means allocation
failure, so suppress this warning info.

Fixes: cf11e85fc08c ("mm: hugetlb: optionally allocate gigantic hugepages using cma")
