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