Enabling High-Performance Storage for RISC-V
summary
Lustre client ported to RISC-V by adding architecture support and three core changes (build target, 64-bit erasure coding paths, fallback header) and landing 7 upstream patches merged to master. Testing uses two QEMU RISC-V VMs (Ubuntu 24.04, kernel 6.8.4) plus an x86_64 server, module loading, mount, file IO and standard benchmarks pass, while MGS/MDS/OSS remain on other architectures. CI with Gerrit/CloudV catches regressions moving forward.
