From c29f7d457ac63311feb11928a866efd2fe153d74 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 30 Nov 2011 08:58:18 +0000 Subject: xfs: fix nfs export of 64-bit inodes numbers on 32-bit kernels The i_ino field in the VFS inode is of type unsigned long and thus can't hold the full 64-bit inode number on 32-bit kernels. We have the full inode number in the XFS inode, so use that one for nfs exports. Note that I've also switched the 32-bit file handles types to it, just to make the code more consistent and copy & paste errors less likely to happen.
