Could you explain why this merging needs to be done in kernel space?
Why not in user-space after the fact? If the individual scripts emit
timestamps, it would be straightforward. By merging in kernel space,
we would probably be forcing all systemtap modules to synchronize
while sharing a single set of buffers, slowing them all down. Can
you describe a scenario where this is worth the cost?
