The following Trac tickets were found above:
Ticket 1029 --> https://svn.open-mpi.org/trac/ompi/ticket/1029
mca_btl_openib_mca_setup_qps(). It looks like someone just forgot to
clean-up the previous call when they added the check for the return
code.
I ran a quick IMB test over IB to verify everything is still working.
This commit was SVN r16870.
A new global structure (ompi_request_functions) holding all the pointers to the wait/test functions have been added. ompi_request_wait* and ompi_request_test* have been #defined to be replaced by ompi_request_functions.req_wait. The default implementations of the wait/test functions names have been changed from ompi_request_% to ompi_request_default_%. Those functions are static initializer of the ompi_request_functions structure.
To modify the defaults, a components 1) copy the ompi_request_functions structure (the type ompi_request_fns_t can be used to declare a suitable variable), 2) change some of the functions according to its needs. This is best done at MPI_init time when there is no threads. Should this component be unloaded it have to restore the defaults. The ompi_request_default_* functions should never be called directly anywhere in the code. If a component needs to access the previously defined implementation of wait, it should call its local copy of the function. Component implementors should keep in mind that another component might have already changed the defaults and needs to be called.

ompi_mtl_portals_finalize(). Previous code was cleaning up Portals resources
that hadn't been allocated, which caused valid handles used elsewhere to be
freed, which broke cnos_barrier() for the Portals btl.

needed instead of creating it and then canceling if it is not needed. Change
error handling during finalize so that it will not skip async thread
destruction. Otherwise async thread may segfault during openib module unloading.

to a pending queue of eager rdma QP instead of correct pending list. This patch
fixes this by getting reed of "eager rdma qp" notion. Packet is always send
over its order QP. The patch also adds two pending queues for high and low prio
packets. Only high prio packets are sent over eager RDMA channel.

main idea (except of cleanup) is to save on initialisation of unneeded fields
and to use C type checking system to catch obvious errors.
