Hi Ben,

what's the point of calling wake_up_locked(&sem->wait) in
aio_down_wait? We're already in a wakeup path and end up
calling __wake_up_common recursively.

I think it may be one of the cause of my kernel hanging at the
very beginning.

When I remove this call things go further but at some point a
semaphore wait queue gets thrashed and __wake_up_common tries to
call an invalid callback function.

Any input appreciated.
