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. ) | |
