+config XFS_FS
+ tristate "XFS filesystem support"
+ select EXPORTFS if NFSD!=n
+ 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_EXPORT
+ bool
+ default y if XFS_FS && EXPORTFS
+
+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.
