Thank you for pointing this out. I've updated my git configuration and 
the patch to ensure the Signed-off-by matches the Author's Gmail address.

Since the probe is now fully stateless and no longer touches per-cpu 
variables, I've opted to remove the redundant cpu_hotplug_disable() in 
v7 to make the code cleaner, as you suggested it wasn't strictly necessary.

Thanks again for your detailed review and guidance!
