Thanks for your patchset. A few comments:

It might be more nice to reuse the existing structures and put
timespec64 to the reserved field and duplicate information (with the
32-bit wrapping for the old fields). It means that we do not need new
ioctls and old libraries will be fine.

It may make sense to define private snd_timespec32 and snd_timespec64
with s32/s64 types instead separate sec/usec fields.
