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
	depends on XFS_FS && EXPORTFS
	default y

config XFS_QUOTA
	bool "XFS 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 "XFS 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 "XFS 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.

config XFS_RT
	bool "XFS 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.
