It is currently possible to configure a kernel address filter for a event that excludes kernel from its traces (attr.exclude_kernel==1). While in reality this doesn't make sense, the SET_FILTER ioctl() should return a error in such case, currently it does not. Furthermore, it will still silently discard the filter and any potentially valid filters that came with it. This patch makes the SET_FILTER ioctl() error out in such cases.
