 This option bit can be employed with all futex operations.

+It tells the kernel that the futex is process-private and not shared
+with another process
+(i.e., it is being used for synchronization between threads).
 This allows the kernel to choose the fast path for validating
 the user-space address and avoids expensive VMA lookups,
 taking reference counts on file backing store, and so on.
