What do you mean by "require filling the padding"?  I thought the 
conclusion in the kernel was that it dealt with zeroing the padding when 
reading a timespec64 from userspace on a 32-bit system (with the caveat of 
that not happening for compat tasks under 64-bit kernels before 5.1.5, and 
so the question in 
<https://sourceware.org/ml/libc-alpha/2019-05/msg00698.html> of whether to 
treat 5.1.0 through 5.1.4 as buggy and unsupported).
