From c01f0b54efb1519f513089984c163ad3f6fea6eb Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 5 Apr 2018 16:22:01 -0700 Subject: [PATCH] mm/ksm.c: make stable_node_dup() static stable_node_dup() is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: mm/ksm.c:1321:13: warning: symbol 'stable_node_dup' was not declared. Should it be static?
