I've been doing some experimenting with locking on 2.4.18 and have
noticed that if I have a number of writers waiting on a lock, they are
not woken up in the order in which they requested the lock.

Is this expected? If so, what was the reasoning for this and are there
any patches to give FIFO wakeups?

Thanks,

Chris
