 * x86_64 has no getrlimit syscall; the prlimit64 ABI serves the read with
 * (pid = 0, resource, new_limit = NULL, old_limit = &rlim). struct rlimit
 * is two 64-bit words here — the same layout as the kernel's struct
 * rlimit64 — so the record passes through without conversion.
 *
 * getrlimit64 is a name-only distinction on this architecture (rlim_t is
 * already 64 bits); it exists as a separate exported symbol so LFS callers
 * that reference it link cleanly.
