From 2efeb8da992b955fa7705259e4b2f5937979deff Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Wed, 24 Feb 2021 12:07:29 -0800 Subject: mm/huge_memory.c: remove unused return value of set_huge_zero_page() The return value of set_huge_zero_page() is always ignored. So we should drop such return value.
