From d6e43f751f252c68ca69fa6d18665d88d69ef8b7 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 14 Jun 2011 00:45:44 +0100 Subject: AFS: Use i_generation not i_version for the vnode uniquifier Store the AFS vnode uniquifier in the i_generation field, not the i_version field of the inode struct. i_version can then be given the AFS data version number.
