Hi! I haven't found an existing report for this problem, but I observed that Linux 6.12-rc1 fails to build like this on aarch64-linux with CONFIG_NFS_LOCALIO=y: /nix/store/f3k0rdhcd2cx57phx755c2xixgifw5m5-binutils-2.42/bin/ld: warning: -z relro ignored /nix/store/f3k0rdhcd2cx57phx755c2xixgifw5m5-binutils-2.42/bin/ld: Unexpected GOT/PLT entries detected!
