NFSv4.1: pnfs: add LAYOUTGET and GETDEVICEINFO infrastructure

2010-10-24T22:07:10+00:00

Add the ability to actually send LAYOUTGET and GETDEVICEINFO.  This also adds
in the machinery to handle layout state and the deviceid cache.  Note that
GETDEVICEINFO is not called directly by the generic layer.  Instead it
is called by the drivers while parsing the LAYOUTGET opaque data in response
to an unknown device id embedded therein.  RFC 5661 only encodes
device ids within the driver-specific opaque data.

NFS: change stateid to be a union

2010-10-24T22:02:53+00:00

In NFSv4.1 the stateid consists of the other and seqid fields. For layout
processing we need to numerically compare the seqid value of layout stateids.
To do so, introduce a union to nfs4_stateid to switch between opaque(16 bytes)
and opaque(12 bytes) / __be32

NFSv4.1: pnfsd, pnfs: protocol level pnfs constants

2010-10-24T22:02:53+00:00

Use only layoutreturn constant for both returns and recalls.
(return_* works better for recall_type rather the other way around)

nfsd4: keep per-session list of connections

2010-10-01T23:29:44+00:00

The spec requires us in various places to keep track of the connections
associated with each session.

NFSv4: Add support for the RELEASE_LOCKOWNER operation

2010-07-30T18:46:10+00:00

This is needed by NFSv4.0 servers in order to keep the number of locking
stateids at a manageable level.

nfs41: RECLAIM_COMPLETE XDR functionality

2009-12-05T21:08:40+00:00

XDR encoding and decoding for RECLAIM_COMPLETE.  Implements the necessary
encoding to indicate reclaim complete for the entire client.  In the future,
it can be extended to provide reclaim complete functionality for a single
file system after migration.

nfs41: check SEQUENCE status flag

2009-12-05T18:46:14+00:00

the server can indicate a number of error conditions by setting the
appropriate bits in the SEQUENCE operation. The client re-establishes
state with the server when it receives one of those, with the action
depending on the specific case.

NFS: Allow the "nfs" file system type to support NFSv4

2009-09-08T23:50:03+00:00

When mounting an "nfs" type file system, recognize "v4," "vers=4," or
"nfsvers=4" mount options, and convert the file system to "nfs4" under
the covers.
