Add the rt linux 4.1.3-rt3 as base
Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> We lose all the git history this way and it's not good. We should apply another opnfv project repo in future. Change-Id: I87543d81c9df70d99c5001fbdf646b202c19f423 Signed-off-by: Yunhong Jiang <yunhong.jiang@intel.com>

+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 lustre client
+tools from
+https://downloads.hpdd.intel.com/public/lustre/latest-feature-release/
+the package name is lustre-client.
+
+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)
