Thank you for your review and suggestion. One of the key points of
meminspect is to be easy to use by the kernel developer. E.g. to be easy
to add another symbol, like `clear_seq` for a particular use case.
So, someone wanting to make use of it, can easily add it.
The purpose of the initial submission would be to have a basic use case
working, and show it as an example for everyone.
If you would like to detail about the features you mention, it could be
interesting to try them and see if it would work with a meminspect dump.
