Hi all, After merging the akpm-current tree, today's linux-next build (x86_64 allmodconfig) produced this warning: net/tipc/sysctl.c:42:12: warning: 'one' defined but not used [-Wunused-variable] static int one = 1; ^~~ net/tipc/sysctl.c:41:12: warning: 'zero' defined but not used [-Wunused-variable] static int zero; ^~~~ Introduced by commit 6a33853c5773 ("proc/sysctl: add shared variables for range check") -- Cheers, Stephen Rothwell
