/**
* There is a limitation on the number of bytes that can be passed into
* the file handle that nfs passes into AFS. The limit is 10 bytes.
* We pass in an array of long of size 2. On a 32 bit system this would be
* 8 bytes. But on a 64 bit system this would be 16 bytes. The first
* element of this array is a pointer so we cannot truncate that. But the
* second element is the AFS_XLATOR_MAGIC, which we can truncate.
* So on a 64 bit system the 10 bytes are used as below
* Bytes 1-8 pointer to vnode
* Bytes 9 and 10 AFS_XLATOR_MAGIC
*
* And hence for 64 bit environments AFS_XLATOR_MAGIC is 8765 which takes
* up 2 bytes
