Using kmalloc means a memory leak when you stop AFS. I don't think
afs_getevent() and afs_addevent() should be a problem. How about just
replacing sleep and wake_up with add_wait_queue/remove_wait_queue ?

I don't know is this is possible. But we don't drop GLOCK on other
OSes. I guess we need to drop GLOCK because we call vmalloc() and
schedule() in a loop in linux_alloc().
