Possible VFS operation layers (per-operation)

These values are used by VFS subsystem when building vfs_ops for connection
from multiple VFS modules. Internally, Samba differentiates only opaque and
transparent layers at this process. Other types are used for providing better
diagnosing facilities.
-

Most modules will provide transparent layers. Opaque layer is for modules
which implement actual file system calls (like DB-based VFS). For example,
default POSIX VFS which is built in into Samba is an opaque VFS module.
-

Other layer types (audit, splitter, scanner) were designed to provide different
degree of transparency and for diagnosing VFS module behaviour.
-
+
Each module can implement several layers at the same time provided that only
one layer is used per each operation.
