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