BTW, your patch set has an awkward order: you have some vfs and ext2/tmpfs
patches, then UM patches, then fallthru patches for specific file systems,
then UM patches again. Is it possible to order them so all UM patches go in
order; all lower-level F/S patches are also sequential; etc.?

Same nit I had before: why add ->fallthru in the middle of inode_operations
and not in the end?
