The purpose of the return value of cmpxchg_futex_value_locked changed in 37a9d912b24f96a0591 "futex: Sanitize cmpxchg_futex_value_locked API" which is not included in 2.6.32. This patch changes the return value to a status code, but in 2.6.32 the return value is the value of the futex or -EFAULT. With this backported patch, any futex with a non-zero value will return -EFAULT.
