From 7a224228ed79d587ece2304869000aad1b8e97dd Mon Sep 17 00:00:00 2001 From: Jean Noel Cordenner Date: Mon, 28 Jan 2008 23:58:27 -0500 Subject: vfs: Add 64 bit i_version support The i_version field of the inode is changed to be a 64-bit counter that is set on every inode creation and that is incremented every time the inode data is modified (similarly to the "ctime" time-stamp). The aim is to fulfill a NFSv4 requirement for rfc3530. This first part concerns the vfs, it converts the 32-bit i_version in the generic inode to a 64-bit, a flag is added in the super block in order to check if the feature is enabled and the i_version is incremented in the vfs.
