128  * probe.  Typically, the SMB request is unmarshalled so that request
129  * specific context can be traced.  This is also a useful place to
130  * allocate memory that will be used throughout the processing of the
131  * command.
132  *
133  * The com-handler performs the requested operation: request validation,
134  * bulk (write) incoming data decode, implementation of the appropriate
135  * algorithm and transmission of a response (as appropriate).
136  *
137  * The post-handler is always called, regardless of success or failure
138  * of the pre or com functions, to trigger the DTrace done probe and
139  * deallocate memory allocated in the pre-handler.
