99  * SMB request handers called from the dispatcher.  Each SMB request
100  * is handled in three phases: pre, com (command) and post.
101  *
102  * The pre-handler is primarily to set things up for the DTrace start
103  * probe.  Typically, the SMB request is unmarshalled so that request
104  * specific context can be traced.  This is also a useful place to
105  * allocate memory that will be used throughout the processing of the
106  * command.
107  *
108  * The com-handler performs the requested operation: request validation,
109  * bulk (write) incoming data decode, implementation of the appropriate
110  * algorithm and transmission of a response (as appropriate).
111  *
112  * The post-handler is always called, regardless of success or failure
113  * of the pre or com functions, to trigger the DTrace done probe and
114  * deallocate memory allocated in the pre-handler.
