 * setrlimit/setrlimit64 (todo 31).

 * The write side of the prlimit64 ABI: (pid = 0, resource,
 * new_limit = &rlim, old_limit = NULL). struct rlimit is the kernel's
 * struct rlimit64 layout on x86_64, so the record passes through without
 * conversion; the kernel rejects a soft limit above the hard limit with
 * EINVAL and a hard-limit raise without CAP_SYS_RESOURCE with EPERM.
 *
 * setrlimit64 is a name-only distinction on this architecture (rlim_t is
 * already 64 bits); it exists as a separate exported symbol for LFS
 * callers.
