70  * SMB request handers called from the dispatcher.  Each SMB request
71  * is handled in three phases: pre, com (command) and post.
72  *
73  * The pre-handler is primarily to set things up for the DTrace start
74  * probe.  Typically, the SMB request is unmarshalled so that request
75  * specific context can be traced.  This is also a useful place to
76  * allocate memory that will be used throughout the processing of the
77  * command.
78  *
79  * The com-handler performs the requested operation: request validation,
80  * bulk (write) incoming data decode, implementation of the appropriate
81  * algorithm and transmission of a response (as appropriate).
82  *
83  * The post-handler is always called, regardless of success or failure
84  * of the pre or com functions, to trigger the DTrace done probe and
85  * deallocate memory allocated in the pre-handler.
