Detailed Description

Query operations for an index service. The operations in this data structure can be divided into 2 groups: (a) Operations over indices: iqo_namei_create/delete/lookup/list. (b) Queries on a specific index: get/put/del/next, see the comments above for details.

Returned value of query operations: = 0: the query is executed synchronously and returns successfully. < 0: the query fails. = 1: the driver successes in launching the query asynchronously.

idx_op_ast_complete()/fail() must be called correspondingly when an index operation is completed successfully or fails. This gives Client a chance to take back control and move operation's state forward.
