Add NFS mount options to allow the local caching support to be enabled.
The attached patch makes it possible for the NFS filesystem to be told to make
use of the network filesystem local caching service (FS-Cache).
To be able to use this, a recent nfsutils package is required.

FS-Cache page management for NFS. This includes hooking the releasing and
invalidation of pages marked with PG_fscache (aka PG_private_2) and waiting for
completion of the write-to-cache flag (PG_fscache_write aka PG_owner_priv_2).

Add read context retention so that FS-Cache can call back into NFS when a read
operation on the cache fails EIO rather than reading data. This permits NFS to
then fetch the data from the server instead using the appropriate security
context.

These patches add local caching for network filesystems such as NFS.
The patches can roughly be broken down into a number of sets:
(*) 01-keys-inc-payload.diff
(*) 02-keys-search-keyring.diff
(*) 03-keys-callout-blob.diff
Three patches to the keyring code made to help the CIFS
Add a 'kernel_service' object class to SELinux and give this object class two
access vectors: 'use_as_override' and 'create_files_as'.
The first vector is used to grant a process the right to nominate an alternate
process security ID for the kernel to use as an override for the SELinux
subjective
Allow the callout data to be passed as a blob rather than a string for internal
kernel services that call any request_key_*() interface other than
request_key(). request_key() itself still takes a NUL-terminated string.
The functions that change are:
request_key_with_auxdata()
Increase the size of a payload that can be used to instantiate a key in
add_key() and keyctl_instantiate_key(). This permits huge CIFS SPNEGO blobs to
be passed around. The limit is raised to 1MB. If kmalloc() can't allocate a
buffer of sufficient size, vmalloc() will be tried instead.

Add a function to install a monitor on the page lock waitqueue for a particular

This is used by CacheFiles to detect read completion on a page in the backing
filesystem so that it can then copy the data to the waiting netfs page.

The unprivileged mounts patches do contain a simple form of access
