-config XFS_FS
- tristate "XFS filesystem support"
- 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.
