In preparation for replaying user affinity requests using a saved mask, split sched_setaffinity() up so that the initial task lookup and security checks are only performed when the request is coming directly from userspace.

Should not sched_setaffinity() update user_cpus_ptr when it isn't NULL, such that the upcoming relax_compatible_cpus_allowed_ptr() preserve the full user mask? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
