The ceph_ioctl function is used both for files and directories, but only the files support doing that in 32-bit compat mode.
For consistency, add the same compat handler to the dir operations as well.
Have you verified that all the relevant ioctl buffer structures are exactly the same for 32bit and 64bit applications?
