Start with this:
https://git.samba.org/?p=samba.git;a=blob;f=source3/smbd/vfs.c#l1458

It gives an overview how all this will be used.
Once the basics are understood, look at the specific implementation
of the wrappers:
https://git.samba.org/?p=samba.git;a=commitdiff;h=2dd95c1c38b9e1ce32d3

Then you can dive into the tevent and pthreadpool changes.

The first SMB_VFS users will follow tomorrow.
