6 | Stores not just filenames but the files themselves in a balanced | |
7 | tree. Uses journalling. | |
8 | ||
9 | Balanced trees are more efficient than traditional file system | |
10 | architectural foundations. | |
11 | ||
12 | In general, ReiserFS is as fast as ext2, but is very efficient with | |
13 | large directories and small files. Additional patches are needed | |

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

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

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

80 | implemented by security modules like SELinux. This option | |
81 | enables an extended attribute handler for file security | |
82 | labels in the ReiserFS filesystem. | |

84 | If you are not using a security module that requires using | |
85 | extended attributes for file security labels, say N. |
