Why did you remove close() from the dazukofs_return_access()? If you
leave close() in dazukofs_return_access(), then there should be no
problem.

It is important that you call dazukofs_return_access() for _every_
access. Otherwise you will not only run out of file descriptors, but
you will also block user processes from completing their open().
