Does it mean Acked-by, Reviewed-by, or something else?

What you ask breaks rules:
Documentation/process/submitting-patches.rst:
Separate each **logical change** into a separate patch.
For example, if your changes include both bug fixes and performance
enhancements for a single driver, separate those changes into two
or more patches. If your changes include an API update, and a new
driver which uses that new API, separate those into two patches.
On the other hand, if you make a single change to numerous files,
group those changes into a single patch. Thus a single logical change
is contained within a single patch.
This is not a dead rule, refer for example the 96d4f267e40f9 ("Remove
'type' argument from access_ok() functioin.")
Or this: https://lkml.org/lkml/2021/6/14/1736
Thanks,
Yury
