Hello!

This series removes spin_unlock_wait():

1. Remove spin_unlock_wait() from net/netfilter/nf_conntrack_core,
courtesy of Manfred Spraul.

2. Replace task_work use of spin_unlock_wait() with lock/unlock
pair, courtesy of Oleg Nesterov.

3. Replace scheduler use of spin_unlock_wait() with lock/unlock pair.

4. Replace completion use of spin_unlock_wait() with lock/unlock
pair.

5. Replace exit() use of spin_unlock_wait() with lock/unlock pair.

6. Replace IPC use of spin_unlock_wait() with lock/unlock pair.

7. Replace ATA use of spin_unlock_wait() with lock/unlock pair.

8. Remove generic definition of spin_unlock_wait().

9. Remove architecture-specific definitions of spin_unlock_wait().

Thanx, Paul
