Christoph's vfs patch looks good, I've stripped out the XFS bits (FS
parts should probably be in different patches) and made one small
change.  freeze/thaw now check to make sure bdev != NULL.

On the device mapper side, I had to add a struct super_block pointer to
the dm struct and changed it to pin the bdev struct during the freeze. 
Before, it could go away due to bdput, leading to deadlock when someone
else got a bdev struct with bd_mount_sem held.

New patches attached, along with an incremental to clearly show my
changes to the dm patch.
