If poll_select_set_timeout - helper function to setup the timeout value*@to: pointer to timespec64 variable for the final timeout*@sec: seconds (from user space)*@nsec: nanoseconds (from user space)* Note, we do not use a timespec for the user space value Then Return -EINVAL

ret = set_compat_user_sigmask(sigmask, sigsetsize)

1321

If ret Then Return ret

1324

ret = We can actually return ERESTARTSYS instead of EINTR, but I'd* like to be certain this leads to no problems. So I return* EINTR just for safety.* Update: ERESTARTSYS breaks at least the xview clock binary, so

1325

Return poll_select_finish( & end_time, tsp, type, ret)
