If the client holds a delegation, it should be able to offer all the
guarantees that are needed to support application leases and
delegations. The main use case here is when re-exporting NFSv4.

Trond Myklebust (4):
  NFSv4: Fix delegation return in cases where we have to retry
  NFSv4: Add lease breakpoints in case of a delegation recall or return
  NFSv4: Add support for application leases underpinned by a delegation
  NFS: nfs_find_open_context() may only select open files
