Hi all, After merging the tip tree, today's linux-next build (powerpc_ppc64 defconfig) produced this warning: kernel/sched/debug.c: In function 'print_cfs_group_stats': kernel/sched/debug.c:460:41: warning: unused variable 'stats' [-Wunused-variable] 460 | struct sched_statistics *stats = __schedstats_from_se(se); | ^~~~~ Caused by commit cb3e971c435d ("sched: Make struct sched_statistics independent of fair sched class") # CONFIG_SCHEDSTATS is not set -- Cheers, Stephen Rothwell
