+config REISERFS_FS
+ tristate "Reiserfs support"
+ help
+ Stores not just filenames but the files themselves in a balanced
+ tree. Uses journalling.
+
+ Balanced trees are more efficient than traditional file system
+ architectural foundations.
+
+ In general, ReiserFS is as fast as ext2, but is very efficient with
+ large directories and small files. Additional patches are needed
+ for NFS and quotas, please see <http://www.namesys.com/> for links.
+
+ It is more easily extended to have features currently found in
+ database and keyword search systems than block allocation based file
+ systems are. The next version will be so extended, and will support
+ plugins consistent with our motto ``It takes more than a license to
+ make source code open.''
+
+ Read <http://www.namesys.com/> to learn more about reiserfs.
+
+ Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com.
+
+ If you like it, you can pay us to add new features to it that you
+ need, buy a support contract, or pay us to port it to another OS.
+
+config REISERFS_CHECK
+ bool "Enable reiserfs debug mode"
+ depends on REISERFS_FS
+ help
+ If you set this to Y, then ReiserFS will perform every check it can
+ possibly imagine of its internal consistency throughout its
+ operation. It will also go substantially slower. More than once we
+ have forgotten that this was on, and then gone despondent over the
+ latest benchmarks.:-) Use of this option allows our team to go all
+ out in checking for consistency when debugging without fear of its
+ effect on end users. If you are on the verge of sending in a bug
+ report, say Y and you might get a useful error message. Almost
+ everyone should say N.
+
+config REISERFS_PROC_INFO
+ bool "Stats in /proc/fs/reiserfs"
+ depends on REISERFS_FS && PROC_FS
+ help
+ Create under /proc/fs/reiserfs a hierarchy of files, displaying
+ various ReiserFS statistics and internal data at the expense of
+ making your kernel or module slightly larger (+8 KB). This also
+ increases the amount of kernel memory required for each mount.
+ Almost everyone but ReiserFS developers and people fine-tuning
+ reiserfs or tracing problems should say N.
+
+config REISERFS_FS_XATTR
+ bool "ReiserFS extended attributes"
+ depends on REISERFS_FS
+ help
+ Extended attributes are name:value pairs associated with inodes by
+ the kernel or by users (see the attr(5) manual page, or visit
+ <http://acl.bestbits.at/> for details).
+
+ If unsure, say N.
+
+config REISERFS_FS_POSIX_ACL
+ bool "ReiserFS POSIX Access Control Lists"
+ depends on REISERFS_FS_XATTR
+ 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 REISERFS_FS_SECURITY
+ bool "ReiserFS Security Labels"
+ depends on REISERFS_FS_XATTR
+ 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 ReiserFS filesystem.
+
+ If you are not using a security module that requires using
+ extended attributes for file security labels, say N.
