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

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

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

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