| |
Hi Rafael,
After merging the pm tree, today's linux-next build (arm multi_v7_defconfig) produced this warning:
kernel/time/tick-sched.c: In function 'tick_nohz_idle_exit': kernel/time/tick-sched.c:1162:3: warning: 'now' may be used uninitialized in this function [-Wmaybe-uninitialized] __tick_nohz_idle_restart_tick(ts, now); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ kernel/time/tick-sched.c:1146:10: note: 'now' was declared here ktime_t now; ^~~
This appears to be a false positive.
And another in the x86_64 allmodconfig build:
kernel/time/tick-sched.c: In function 'tick_nohz_idle_exit': kernel/time/tick-sched.c:538:2: warning: 'now' may be used uninitialized in this function [-Wmaybe-uninitialized] update_ts_time_stats(smp_processor_id(), ts, now, NULL); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ kernel/time/tick-sched.c:1146:10: note: 'now' was declared here ktime_t now; ^~~
also looks like a false positive.
