6 | Reiserfs is deprecated and scheduled to be removed from the kernel |
7 | in 2025. If you are still using it, please migrate to another | |
8 | filesystem or tell us your usecase for reiserfs. | |
9 | ||
10 | Reiserfs stores not just filenames but the files themselves in a | |
11 | balanced tree. Uses journalling. | |
b16ecfe2 AD |
12 | |
13 | Balanced trees are more efficient than traditional file system | |
14 | architectural foundations. | |
15 | ||
16 | In general, ReiserFS is as fast as ext2, but is very efficient with | |
17 | large directories and small files. Additional patches are needed | |

21 | It is more easily extended to have features currently found in | |
22 | database and keyword search systems than block allocation based file | |
23 | systems are. The next version will be so extended, and will support | |
24 | plugins consistent with our motto ``It takes more than a license to | |
25 | make source code open.'' | |

32 | If you like it, you can pay us to add new features to it that you | |
33 | need, buy a support contract, or pay us to port it to another OS. | |

35 | config REISERFS_CHECK | |
36 | bool "Enable reiserfs debug mode" | |
37 | depends on REISERFS_FS | |
38 | help | |
39 | If you set this to Y, then ReiserFS will perform every check it can | |
40 | possibly imagine of its internal consistency throughout its | |
41 | operation. It will also go substantially slower. More than once we | |
42 | have forgotten that this was on, and then gone despondent over the | |
43 | latest benchmarks.:-) Use of this option allows our team to go all | |
44 | out in checking for consistency when debugging without fear of its | |
45 | effect on end users. If you are on the verge of sending in a bug | |
46 | report, say Y and you might get a useful error message. Almost | |
47 | everyone should say N. | |

52 | help | |
53 | Create under /proc/fs/reiserfs a hierarchy of files, displaying | |
54 | various ReiserFS statistics and internal data at the expense of | |
55 | making your kernel or module slightly larger (+8 KB). This also | |
56 | increases the amount of kernel memory required for each mount. | |
57 | Almost everyone but ReiserFS developers and people fine-tuning | |
58 | reiserfs or tracing problems should say N. | |

63 | help | |
64 | Extended attributes are name:value pairs associated with inodes by | |
91581e4c | 65 | the kernel or by users (see the attr(5) manual page for details). |

74 | Posix Access Control Lists (ACLs) support permissions for users and | |
75 | groups beyond the owner/group/world scheme. | |

81 | depends on REISERFS_FS_XATTR | |
82 | help | |
83 | Security labels support alternative access control models | |
84 | implemented by security modules like SELinux. This option | |
85 | enables an extended attribute handler for file security | |
86 | labels in the ReiserFS filesystem. | |
87 | ||
88 | If you are not using a security module that requires using | |
89 | extended attributes for file security labels, say N. |
