J. Bruce Fields 353601e7d3 nfsd: create a separate lease for each delegation
Currently we only take one vfs-level delegation (lease) for each file,
no matter how many clients hold delegations on that file.

Let's instead keep a one-to-one mapping between NFSv4 delegations and
VFS delegations.  This turns out to be simpler.

There is still a many-to-one mapping of NFS opens to NFS files, and the
delegations on one file are all associated with one struct file.  The
VFS can still distinguish between these delegations since we're setting
fl_owner to the struct nfs4_delegation now, not to the shared file.

I'm replacing at least one complicated function wholesale, which I don't
like to do, but I haven't figured out how to do this more incrementally.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
