signal/signalfd: Remove __put_user from signalfd_copyinfo Put a signalfd_siginfo structure on the stack fully initializae it and then copy it to userspace. The code is a little less wordy, and this avoids a long series of the somewhat costly __put_user calls. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
