[PATCH 0/3] NFS: Add READ_PLUS support

[Anna Schumaker <Anna.Schumaker@netapp.com>]

These patches add client support for the NFS v4.2 operation READ_PLUS.  This
operation is triggered by doing any kind of read on a NFS v4.2 mounted
filesystem.  `

The spec allows for the server to return multiple data and hole segments when
reading a file.  Supporting this would requre a tedious amount of shifiting
to make sure data is aligned properly, so I'm skipping this feature until I
figure out a clean way of coding it.

These patches and the corresponding server changes are available in the
[read_plus] branch of

	git://git.linux-nfs.org/projects/anna/linux-nfs.git

Questions?  Comments?  Thoughts?
