From 4eb0716e868eed963967adb0b1b11d9bd8ca1d01 Mon Sep 17 00:00:00 2001 From: Alexandre Ghiti Date: Mon, 13 May 2019 17:19:04 -0700 Subject: hugetlb: allow to free gigantic pages regardless of the configuration On systems without CONTIG_ALLOC activated but that support gigantic pages, boottime reserved gigantic pages can not be freed at all. This patch simply enables the possibility to hand back those pages to memory allocator.
