Isn't SMP is default for most of the kernel builds? And honestly I didn't get the purpose of this comment. > With what config/kernel are you getting this? x86_64_defconfig from the kernel sources with some drivers added (SMP or so has not been touched, DEBUG_SHED was enabled once to confirm that another static const has same issue). -- With Best Regards, Andy Shevchenko
