105  * SMB request handers called from the dispatcher.  Each SMB request
106  * is handled in three phases: pre, com (command) and post.
107  *
108  * The pre-handler is primarily to set things up for the DTrace start
109  * probe.  Typically, the SMB request is unmarshalled so that request
110  * specific context can be traced.  This is also a useful place to
111  * allocate memory that will be used throughout the processing of the
112  * command.
113  *
114  * The com-handler performs the requested operation: request validation,
115  * bulk (write) incoming data decode, implementation of the appropriate
116  * algorithm and transmission of a response (as appropriate).
117  *
118  * The post-handler is always called, regardless of success or failure
119  * of the pre or com functions, to trigger the DTrace done probe and
120  * deallocate memory allocated in the pre-handler.
