* Add some more error checking to GREQUEST_START * Move the error checking in GREQUEST_COMPLETE up to inside the MPI_PARAM_CHECK block, where it belongs * Invoke the gen request query_fn in all the Right spots (per MPI-2:8.2) * Distinguish between grequests created from C and Fortran * Use the OBJ system to reference count to release the grequest at the Right time and invoke the grequest free_fn properly (see lengthy comment in grequest.c above the destructor) * Have ompi_grequest_complete() call ompi_request_complete() rather than [poorly] copy the contents of ompi_request_complete() * Fix Fortran function callback pointer typedefs to use proper Fortran types * Edit ompi_request_test* and ompi_request_wait* to properly handle generalized requests. This adds an "if" statement in the critical path for all the back-end test* and wait* functions :-(, but fortunately George took out two "if" statements from the critical path last week. So we're still ahead. :-) * Move ompi_request_test() out of request.h and into request.c (all other test* and wait* functions were already in the .c file -- and ompi_request_test() was too long to be statically inlined anyway) This commit was SVN r12402.
