So, if I understand correctly, we might have a new librados::aio_exec_completion call that accepts a completion object? For example: aio_exec_completion(AioCompletion *c, bufferlist *outbl, ObjectOperationCompletion* completion) { Context *onack = new C_aio_Ack(c); ::ObjectOperation rd; ObjectOpCompletionCtx *ctx = new ObjectOpCompletionCtx(completion); rd.call(cls, method, inbl, ctx->outbl, ctx, NULL); objecter->read(oid, oloc, rd, snap_seq, outbl, 0, onack, &c->objver); return 0; } where the caller would provide an ObjectOperationCompletion where it's finish(..) would unwrap the protocol? Do you expect wip-librados-exec going up stream pretty soon, and would something like librados::aio_exec_completion be a candidate for adding to librados?
