+config JFS_FS
+ tristate "JFS filesystem support"
+ select NLS
+ help
+ This is a port of IBM's Journaled Filesystem . More information is
+ available in the file <file:Documentation/filesystems/jfs.txt>.
+
+ If you do not intend to use the JFS filesystem, say N.
+
+config JFS_POSIX_ACL
+ bool "JFS POSIX Access Control Lists"
+ depends on JFS_FS
+ select FS_POSIX_ACL
+ 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 JFS_SECURITY
+ bool "JFS Security Labels"
+ depends on JFS_FS
+ help
+ Security labels support alternative access control models
+ implemented by security modules like SELinux. This option
+ enables an extended attribute handler for file security
+ labels in the jfs filesystem.
+
+ If you are not using a security module that requires using
+ extended attributes for file security labels, say N.
+
+config JFS_DEBUG
+ bool "JFS debugging"
+ depends on JFS_FS
+ help
+ If you are experiencing any problems with the JFS filesystem, say
+ Y here. This will result in additional debugging messages to be
+ written to the system log. Under normal circumstances, this
+ results in very little overhead.
+
+config JFS_STATISTICS
+ bool "JFS statistics"
+ depends on JFS_FS
+ help
+ Enabling this option will cause statistics from the JFS file system
+ to be made available to the user in the /proc/fs/jfs/ directory.
