Subject: Fix f_version type: should be u64 instead of unsigned long

Fix f_version type: should be u64 instead of long

There is a type inconsistency between struct inode i_version and struct file
f_version.

fs.h:

struct inode
  u64                     i_version;

and

struct file
  unsigned long           f_version;

Users do:

fs/ext3/dir.c:

if (filp->f_version != inode->i_version) {

So why isn't f_version a u64 ? It becomes a problem if versions gets
higher than 2^32 and we are on an architecture where longs are 32 bits.

This patch changes the f_version type to u64, and updates the users accordingly.

It applies to 2.6.23-rc2-mm2.
