Sure, but that's done :)

You put the changes into 3 files:
lib/tst_checkpoint.c
testcases/kernel/syscalls/clone/clone08.c
testcases/kernel/syscalls/futex/futextest.h

Check the affected files:

I put changes into include/lapi/futex.h
and load it in
testcases/kernel/syscalls/clone/clone08.c

The other two (testcases/kernel/syscalls/clone/clone08.c
testcases/kernel/syscalls/futex/futextest.h) already include lapi/futex.h.

Are you sure it's failing when you try my patchset?

Kind regards,
Petr
