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 | |
14 | for NFS and quotas, please see <http://www.namesys.com/> for links. | |
15 | ||
16 | It is more easily extended to have features currently found in | |
17 | database and keyword search systems than block allocation based file | |
18 | systems are. The next version will be so extended, and will support | |
19 | plugins consistent with our motto ``It takes more than a license to | |
20 | make source code open.'' | |

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

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

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

54 | config REISERFS_FS_XATTR | |
55 | bool "ReiserFS extended attributes" | |
56 | depends on REISERFS_FS | |
57 | help | |
58 | Extended attributes are name:value pairs associated with inodes by | |
59 | the kernel or by users (see the attr(5) manual page, or visit | |
60 | <http://acl.bestbits.at/> for details). | |
61 | ||
62 | If unsure, say N. | |

68 | help | |
69 | Posix Access Control Lists (ACLs) support permissions for users and | |
70 | groups beyond the owner/group/world scheme. | |
71 | ||
72 | To learn more about Access Control Lists, visit the Posix ACLs for | |
73 | Linux website <http://acl.bestbits.at/>. | |

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