rdma-mummy-sys 0.2.4 uses bindgen 0.66, which emits opaque ibverbs structs with LLVM 22. Require 0.2.5, whose bindgen 0.72 update restores the generated fields. Add a compile regression test for representative ibv_context and ibv_mr fields.

Summary
rdma-mummy-sys0.2.5 directly inopeninfer-kv-offload.The pinned
pegaflow-corerevision permits 0.2.4, so this requirementraises the resolver's minimum version.
Cargo.locktordma-mummy-sys0.2.5. Its bindgen update removesobsolete transitive dependencies from the lockfile.
ibv_context.opsandibv_mr.lkey.Motivation
With LLVM/libclang 22, bindgen 0.66 generates vendored rdma-core structs such
as
ibv_contextas opaque_addressshells.rdma-mummy-sys0.2.4 thenfails to compile when its wrapper accesses fields such as
ops,context,and
lkey.rdma-mummy-sys0.2.5 upgrades bindgen to 0.72.1 to support LLVM 22(upstream commit).
Impact
OpenInfer now builds when bindgen loads libclang 22, without overriding
LIBCLANG_PATHto select an older installation. RDMA runtime behavior isunchanged.
Validation
cargo fmt --checkenv -u LIBCLANG_PATH CUDA_HOME=/opt/cuda cargo check --release -p openinfer-serverenv -u LIBCLANG_PATH CUDA_HOME=/opt/cuda cargo test --release -p openinfer-kv-offload --test rdma_bindingsThe release check and regression test pass with libclang 22.
