Applied to the testing branch and will run the tests. Thanks Luis.

Function ceph_get_inode() never returns NULL; instead it returns an ERR_PTR() if something fails. Thus, the check for NULL in parse_longname() is useless and can be dropped. Instead, move there the debug code that does the error checking so that it's only executed if ceph_get_inode() is called.
