Does the following function have folio version?

No -- I haven't needed to convert anything that uses
sg_alloc_append_table_from_pages() yet. It doesn't look like it should
be _too_ hard to add a folio version.
In many places, this function is used. So this function needs the folio
version.
Another problem, after folio is used, I want to know the performance
after folio is implemented.
How to make tests to get the performance?
Thanks a lot.
