5 | Stores not just filenames but the files themselves in a balanced |
6 | tree. Uses journalling. |
7 | |
8 | Balanced trees are more efficient than traditional file system |
9 | architectural foundations. |
10 | |
11 | In general, ReiserFS is as fast as ext2, but is very efficient with |
12 | large directories and small files. Additional patches are needed |
13 | for NFS and quotas, please see <http://www.namesys.com/> for links. |
14 | |
15 | It is more easily extended to have features currently found in |
16 | database and keyword search systems than block allocation based file |
17 | systems are. The next version will be so extended, and will support |
18 | plugins consistent with our motto ``It takes more than a license to |
19 | make source code open.'' |

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

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

42 | config REISERFS_PROC_INFO |
43 | bool "Stats in /proc/fs/reiserfs" |
44 | depends on REISERFS_FS && PROC_FS |
45 | help |
46 | Create under /proc/fs/reiserfs a hierarchy of files, displaying |
47 | various ReiserFS statistics and internal data at the expense of |
48 | making your kernel or module slightly larger (+8 KB). This also |
49 | increases the amount of kernel memory required for each mount. |
50 | Almost everyone but ReiserFS developers and people fine-tuning |
51 | reiserfs or tracing problems should say N. |
52 | |
53 | config REISERFS_FS_XATTR |
54 | bool "ReiserFS extended attributes" |
55 | depends on REISERFS_FS |
56 | help |
57 | Extended attributes are name:value pairs associated with inodes by |
58 | the kernel or by users (see the attr(5) manual page, or visit |
59 | <http://acl.bestbits.at/> for details). |
60 | |
61 | If unsure, say N. |
62 | |
63 | config REISERFS_FS_POSIX_ACL |
64 | bool "ReiserFS POSIX Access Control Lists" |
65 | depends on REISERFS_FS_XATTR |
66 | select FS_POSIX_ACL |
67 | help |
68 | Posix Access Control Lists (ACLs) support permissions for users and |
69 | groups beyond the owner/group/world scheme. |
70 | |
71 | To learn more about Access Control Lists, visit the Posix ACLs for |
72 | Linux website <http://acl.bestbits.at/>. |
73 | |
74 | If you don't know what Access Control Lists are, say N |
75 | |
76 | config REISERFS_FS_SECURITY |
77 | bool "ReiserFS Security Labels" |
78 | depends on REISERFS_FS_XATTR |
79 | help |
80 | Security labels support alternative access control models |
81 | implemented by security modules like SELinux. This option |
82 | enables an extended attribute handler for file security |
83 | labels in the ReiserFS filesystem. |
84 | |
85 | If you are not using a security module that requires using |
86 | extended attributes for file security labels, say N. |
