64 bit ino support for NFS client
Hi. Attached is a patch to modify the NFS client code to support 64 bit ino's, as appropriate for the system and the NFS protocol version. The code basically just expand the NFS interfaces for routines which handle ino's from using ino_t to u64 and then uses the fileid in the nfs_inode instead of i_ino in the inode. The code paths that were updated are in the getattr method and the readdir methods. This should be no real change on 64 bit platforms. Since the ino_t is an unsigned long, it would already be 64 bits wide. Thanx... ps Signed-off-by: Peter Staubach <staubach@redhat.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
