The patch titled
64 bit ino support for NFS client
has been removed from the -mm tree. Its filename was
64-bit-ino-support-for-nfs-client.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: 64 bit ino support for NFS client
From: Peter Staubach <staubach@xxxxxxxxxx>
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.
