Created attachment 946426 [details] output from `strace -e trace=file irqbalance --debug --oneshot` Description of problem: If irqbalance doesn't have right to change irq smp affinity it will silliently continue without any warning in logs what so ever. How reproducible: Run irqbalance with Steps to Reproduce: 1. log yourself as regular user 2. set IRQBALANCE_BANNED_CPUS 3. run irqbalancer 4. check /proc/irq/*/smp_affinity if was changed by irqbalance to value coresponding with IRQBALANCE_BANNED_CPUS (if you've done everything right value should stay unchanged due lack of privileges) 5. check irqbalance log (you'll see nothing about failing to set SMP affinity) Expected results: I belive I should be able to at least see some warning in logs about failing to set SMP affinity Additional info: In attachment I'm sending output from my run of `strace -e trace=file irqbalance --debug --oneshot`
