+	help
+	  XFS is a high performance journaling filesystem which originated
+	  on the SGI IRIX platform.  It is completely multi-threaded, can
+	  support large files and large filesystems, extended attributes,
+	  variable block sizes, is extent based, and makes extensive use of
+	  Btrees (directories, extents, free space) to aid both performance
+	  and scalability.
+
+	  Refer to the documentation at <http://oss.sgi.com/projects/xfs/>
+	  for complete details.  This implementation is on-disk compatible
+	  with the IRIX version of XFS.
+
+	  To compile this file system support as a module, choose M here: the
+	  module will be called xfs.  Be aware, however, that if the file
+	  system of your root partition is compiled as a module, you'll need
+	  to use an initial ramdisk (initrd) to boot.
+
+config XFS_RT
+	bool "Realtime support (EXPERIMENTAL)"
+	depends on XFS_FS && EXPERIMENTAL
+	help
+	  If you say Y here you will be able to mount and use XFS filesystems
+	  which contain a realtime subvolume. The realtime subvolume is a
+	  separate area of disk space where only file data is stored. The
+	  realtime subvolume is designed to provide very deterministic
+	  data rates suitable for media streaming applications.
+
+	  See the xfs man page in section 5 for a bit more information.
+
+	  This feature is unsupported at this time, is not yet fully
+	  functional, and may cause serious problems.
+
+	  If unsure, say N.
+
+config XFS_QUOTA
+	bool "Quota support"
+	depends on XFS_FS
+	help
+	  If you say Y here, you will be able to set limits for disk usage on
+	  a per user and/or a per group basis under XFS.  XFS considers quota
+	  information as filesystem metadata and uses journaling to provide a
+	  higher level guarantee of consistency.  The on-disk data format for
+	  quota is also compatible with the IRIX version of XFS, allowing a
+	  filesystem to be migrated between Linux and IRIX without any need
+	  for conversion.
+
+	  If unsure, say N.  More comprehensive documentation can be found in
+	  README.quota in the xfsprogs package.  XFS quota can be used either
+	  with or without the generic quota support enabled (CONFIG_QUOTA) -
+	  they are completely independent subsystems.
+
+config XFS_SECURITY
+	bool "Security Label support"
+	depends on XFS_FS
+	help
+	  Security labels support alternative access control models
+	  implemented by security modules like SELinux.  This option
+	  enables an extended attribute namespace for inode security
+	  labels in the XFS filesystem.
+
+	  If you are not using a security module that requires using
+	  extended attributes for inode security labels, say N.
+
+config XFS_POSIX_ACL
+	bool "POSIX ACL support"
+	depends on XFS_FS
+	help
+	  POSIX Access Control Lists (ACLs) support permissions for users and
+	  groups beyond the owner/group/world scheme.
+
+	  To learn more about Access Control Lists, visit the POSIX ACLs for
+	  Linux website <http://acl.bestbits.at/>.
+
+	  If you don't know what Access Control Lists are, say N.
