Since f35093f8 semantics of a thread affinity functions is changed to be a compatible with Linux: In case of getaffinity(), the minimum cpuset_t size that the kernel permits is the maximum CPU id, present in the system, / NBBY bytes, the maximum size is not limited. In case of setaffinity(), the kernel does not limit the size of the user-provided cpuset_t, internally using only the meaningful part of the set, where the upper bound is the maximum CPU id, present in the system, no larger than the size of the kernel cpuset_t. To match pthread_attr_[g|s]etaffinity_np checks of the user-provided cpusets to the kernel behavior export the minimum cpuset_t size allowed by running kernel via new sysctl kern.sched.cpusetsizemin and use it in checks.
