Pull orangefs filesystem from Mike Marshall.
This finally merges the long-pending orangefs filesystem, which has been
much cleaned up with input from Al Viro over the last six months. From
the documentation file:
"OrangeFS is an LGPL userspace scale-out parallel storage system. It
is ideal for large storage problems faced by HPC, BigData, Streaming
Video, Genomics, Bioinformatics.
Orangefs, originally called PVFS, was first developed in 1993 by Walt
Ligon and Eric Blumer as a parallel file system for Parallel Virtual
Machine (PVM) as part of a NASA grant to study the I/O patterns of
parallel programs.
Orangefs features include:
- Distributes file data among multiple file servers
- Supports simultaneous access by multiple clients
- Stores file data and metadata on servers using local file system
and access methods
- Userspace implementation is easy to install and maintain
- Direct MPI support
- Stateless"
see Documentation/filesystems/orangefs.txt for more in-depth details.

Direct Access (DAX) can be used on memory-backed block devices.
|
|
If the block device supports DAX and the filesystem supports DAX,
|
|
then you can avoid using the pagecache to buffer I/Os. Turning
|
|
on this option will compile in support for DAX; you will need to
|
|
mount the filesystem using the -o dax option.

If you do not have a block device that is capable of using this,

or if unsure, say N. Saying Y will increase the size of the kernel

Tmpfs is a file system which keeps all files in virtual memory.
|
|
|
|
Everything in tmpfs is temporary in the sense that no files will be
|
|
created on your hard drive. The files live in memory and swap
|
|
space. If you unmount a tmpfs instance, everything stored therein is
|
|
lost.

See <file:Documentation/filesystems/tmpfs.txt> for details.

POSIX Access Control Lists (ACLs) support additional access rights
|
|
for users and groups beyond the standard owner/group/world scheme,
|
|
and this option selects support for ACLs specifically for tmpfs
|
|
filesystems.
|
|
|
|
If you've selected TMPFS, it's possible that you'll also need
|
|
this option as there are a number of Linux distros that require
|
|
POSIX ACL support under /dev for certain features to work properly.
|
|
For example, some distros need this feature for ALSA-related /dev
|
|
files for sound to work properly. In short, if you're not sure,
|
|
say Y.

You need this for POSIX ACL support on tmpfs.
