Looks good to me. If we confirm this fixes user's issue on aurora, I think we can merge.

@raffenet I located the issue. In -

mpich/src/mpid/ch4/src/ch4_recv.h

Lines 36 to 41 in a111912

	if (!MPIR_Request_is_complete(*request) && !MPIDIG_REQUEST_IN_PROGRESS(*request)) {
	MPIR_Request *nm_rreq = NULL;
	mpi_errno = MPIDI_NM_mpi_irecv(buf, count, datatype, rank, tag, comm, attr,
	av, &nm_rreq, *request);
	MPIR_ERR_CHECK(mpi_errno);
	/* if netmod recv is not matched yet, attach it to the shm request's partner */

The shm request got completed when we use MPIDI_OFI_CALL_RETRY for fi_trecv, and the progress between retry completed the request before we can set up the anysrc_partner.
