-/* Low-level locks use a combination of atomic operations (to acquire and
- release lock ownership) and futex operations (to block until the state
- of a lock changes). A lock can be in one of three states:
- 0: not acquired,
- 1: acquired with no waiters; no other threads are blocked or about to block
- for changes to the lock state,
- >1: acquired, possibly with waiters; there may be other threads blocked or
- about to block for changes to the lock state.
-
- We expect that the common case is an uncontended lock, so we just need
- to transition the lock between states 0 and 1; releasing the lock does
- not need to wake any other blocked threads. If the lock is contended
- and a thread decides to block using a futex operation, then this thread
- needs to first change the state to >1; if this state is observed during
- lock release, the releasing thread will wake one of the potentially
- blocked threads.
-
- Much of this code takes a 'private' parameter. This may be:
- LLL_PRIVATE: lock only shared within a process
- LLL_SHARED: lock may be shared across processes.
-
- Condition variables contain an optimization for broadcasts that requeues
- waiting threads on a lock's futex. Therefore, there is a special
- variant of the locks (whose name contains "cond") that makes sure to
- always set the lock state to >1 and not just 1.
-
- Robust locks set the lock to the id of the owner. This allows detection
- of the case where the owner exits without releasing the lock. Flags are
- OR'd with the owner id to record additional information about lock state.
- Therefore the states of robust locks are:
- 0: not acquired
- id: acquired (by user identified by id & FUTEX_TID_MASK)
-
- The following flags may be set in the robust lock value:
- FUTEX_WAITERS - possibly has waiters
- FUTEX_OWNER_DIED - owning user has exited without releasing the futex. */
