Linus Torvalds 048ccca8c1 Initial roundup of 4.5 merge window patches 
- Remove usage of ib_query_device and instead store attributes in
   ib_device struct
 - Move iopoll out of block and into lib, rename to irqpoll, and use
   in several places in the rdma stack as our new completion queue
   polling library mechanism.  Update the other block drivers that
   already used iopoll to use the new mechanism too.
 - Replace the per-entry GID table locks with a single GID table lock
 - IPoIB multicast cleanup
 - Cleanups to the IB MR facility
 - Add support for 64bit extended IB counters
 - Fix for netlink oops while parsing RDMA nl messages
 - RoCEv2 support for the core IB code
 - mlx4 RoCEv2 support
 - mlx5 RoCEv2 support
 - Cross Channel support for mlx5
 - Timestamp support for mlx5
 - Atomic support for mlx5
 - Raw QP support for mlx5
 - MAINTAINERS update for mlx4/mlx5
 - Misc ocrdma, qib, nes, usNIC, cxgb3, cxgb4, mlx4, mlx5 updates
 - Add support for remote invalidate to the iSER driver (pushed through the
   RDMA tree due to dependencies, acknowledged by nab)
 - Update to NFSoRDMA (pushed through the RDMA tree due to dependencies,
   acknowledged by Bruce)

Lustre Parallel Filesystem Client
=================================

The Lustre file system is an open-source, parallel file system
that supports many requirements of leadership class HPC simulation
environments.
Born from from a research project at Carnegie Mellon University,
the Lustre file system is a widely-used option in HPC.
The Lustre file system provides a POSIX compliant file system interface,
can scale to thousands of clients, petabytes of storage and
hundreds of gigabytes per second of I/O bandwidth.

Unlike shared disk storage cluster filesystems (e.g. OCFS2, GFS, GPFS),
Lustre has independent Metadata and Data servers that clients can access
in parallel to maximize performance.

In order to use Lustre client you will need to download the "lustre-client"
package that contains the userspace tools from http://lustre.org/download/

You will need to install and configure your Lustre servers separately.

Mount Syntax
============
After you installed the lustre-client tools including mount.lustre binary
you can mount your Lustre filesystem with:

mount -t lustre mgs:/fsname mnt

where mgs is the host name or ip address of your Lustre MGS(management service)
fsname is the name of the filesystem you would like to mount.


Mount Options
=============

  noflock
	Disable posix file locking (Applications trying to use
	the functionality will get ENOSYS)

  localflock
	Enable local flock support, using only client-local flock
	(faster, for applications that require flock but do not run
	 on multiple nodes).

  flock
	Enable cluster-global posix file locking coherent across all
	client nodes.

  user_xattr, nouser_xattr
	Support "user." extended attributes (or not)

  user_fid2path, nouser_fid2path
	Enable FID to path translation by regular users (or not)

  checksum, nochecksum
	Verify data consistency on the wire and in memory as it passes
	between the layers (or not).

  lruresize, nolruresize
	Allow lock LRU to be controlled by memory pressure on the server
	(or only 100 (default, controlled by lru_size proc parameter) locks
	 per CPU per server on this client).

  lazystatfs, nolazystatfs
	Do not block in statfs() if some of the servers are down.

  32bitapi
	Shrink inode numbers to fit into 32 bits. This is necessary
	if you plan to reexport Lustre filesystem from this client via
	NFSv4.

  verbose, noverbose
	Enable mount/umount console messages (or not)

More Information
================
You can get more information at the Lustre website: http://wiki.lustre.org/
