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. > Given our newest understanding, the cpu_hotplug_disable() isn't truly > needed anymore, but I'm still good keeping it. 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. v7 Link: https://lore.kernel.org/all/20260128060833.1715622-1-realwujing@gmail.com/ Thanks again for your detailed review and guidance!
