From: "J. Bruce Fields" <redacted>

These patches move a little more of the change attribute logic into the
filesystems.  They should let us skip a few unnecessary stats, and use
the source filesystem's change attribute in the NFS reexport case.

Do this look reasonable to everyone else?

J. Bruce Fields (3):
  nfs: use change attribute for NFS re-exports
  nfsd: move change attribute generation to filesystem
  nfsd: skip some unnecessary stats in the v4 case
