vfs.c has all the handling for the VFS plugin mechanism, as well as
various utility functions.

vfs-wrap.c is the "default module".  If no VFS module exists that
provides the functions defined in vfs-wrap.c, then vfs-wrap's functions
are called.

non-bugfix changes that you make would most likely go into your own vfs
module.

For code in a VFS module to be called, it must either be one of the
defined functions in vfs_ops, or it must be called from one of those
functions.

Every vfs call has a connection_struct as its first argument.  A quick
look at include/smb.h reveals that one of the items in that struct is:

    char client_address[18]; /* String version of client IP address. */
