| 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. |

| 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. |
