/*
* 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.
