To get the changes in:
78f6face5af3 ("sched: add kernel-doc for struct clone_args")
f14c234b4bc5 ("clone3: switch to copy_struct_from_user()")
This file gets rebuilt, but no changes ensues:
CC /tmp/build/perf/trace/beauty/clone.o
This addresses this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/linux/sched.h' differs from latest version at 'include/uapi/linux/sched.h'
