From 31aafb45f4e1c34e4aba37c150ae4e74880b46ed Mon Sep 17 00:00:00 2001 From: Nicholas Krause Date: Fri, 4 Sep 2015 15:47:58 -0700 Subject: [PATCH] mm/hugetlb.c: make vma_shareable() return bool This makes vma_shareable() return bool now due to this particular function only ever returning either one or zero as its return value.
