84  * SMB request handers called from the dispatcher.  Each SMB request
85  * is handled in three phases: pre, com (command) and post.
86  *
87  * The pre-handler is primarily to set things up for the DTrace start
88  * probe.  Typically, the SMB request is unmarshalled so that request
89  * specific context can be traced.  This is also a useful place to
90  * allocate memory that will be used throughout the processing of the
91  * command.
92  *
93  * The com-handler performs the requested operation: request validation,
94  * bulk (write) incoming data decode, implementation of the appropriate
95  * algorithm and transmission of a response (as appropriate).
96  *
97  * The post-handler is always called, regardless of success or failure
98  * of the pre or com functions, to trigger the DTrace done probe and
99  * deallocate memory allocated in the pre-handler.
