From ae18d6dcf57b56b984ff27fd55b4e2caf5bfbd44 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Tue, 8 Sep 2015 14:59:14 -0700 Subject: [PATCH] thp: change insert_pfn's return type to void It would make more sense to have all the return values from vmf_insert_pfn_pmd() encoded in one place instead of having to follow the convention into insert_pfn().
