281 # The CPU affinity system calls were introduced in Linux kernel 2.5.8.
282 # The library interfaces were introduced in glibc 2.3. Initially, the
283 # glibc interfaces included a cpusetsize argument. In glibc 2.3.3,
284 # the cpuset size argument was removed, but this argument was
285 # restored in glibc 2.3.4.
