| 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.'' |

| 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. |

| 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. |

| 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 | |

| 68 | Posix Access Control Lists (ACLs) support permissions for users and |

| 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. |
