- tristate "Reiserfs support (deprecated)"
- select CRC32
- help
- Reiserfs is deprecated and scheduled to be removed from the kernel
- in 2025. If you are still using it, please migrate to another
- filesystem or tell us your usecase for reiserfs.
- Reiserfs 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
- <https://reiser4.wiki.kernel.org/index.php/Main_Page> 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 <https://reiser4.wiki.kernel.org/index.php/Main_Page>
- 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 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.
- 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.
