8 * a different rlimit ID order in the 5-9 range and want
9 * to keep that order for binary compatibility. The reasons
10 * are historic and all new rlimits are identical across all
11 * arches. If an arch has such special order for some rlimits
12 * then it defines them prior including asm-generic/resource.h. )
