1 config REISERFS_FS 2 tristate "Reiserfs support" 3 select CRC32 4 help 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 14 <https://reiser4.wiki.kernel.org/index.php/Main_Page> 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.'' 21 22 Read <https://reiser4.wiki.kernel.org/index.php/Main_Page> 23 to learn more about reiserfs. 24 25 Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com. 26 27 If you like it, you can pay us to add new features to it that you 28 need, buy a support contract, or pay us to port it to another OS. 29 30 config REISERFS_CHECK 31 bool "Enable reiserfs debug mode" 32 depends on REISERFS_FS 33 help 34 If you set this to Y, then ReiserFS will perform every check it can 35 possibly imagine of its internal consistency throughout its 36 operation. It will also go substantially slower. More than once we 37 have forgotten that this was on, and then gone despondent over the 38 latest benchmarks.:-) Use of this option allows our team to go all 39 out in checking for consistency when debugging without fear of its 40 effect on end users. If you are on the verge of sending in a bug 41 report, say Y and you might get a useful error message. Almost 42 everyone should say N. 43 44 config REISERFS_PROC_INFO 45 bool "Stats in /proc/fs/reiserfs" 46 depends on REISERFS_FS && PROC_FS 47 help 48 Create under /proc/fs/reiserfs a hierarchy of files, displaying 49 various ReiserFS statistics and internal data at the expense of 50 making your kernel or module slightly larger (+8 KB). This also 51 increases the amount of kernel memory required for each mount. 52 Almost everyone but ReiserFS developers and people fine-tuning 53 reiserfs or tracing problems should say N. 54 55 config REISERFS_FS_XATTR 56 bool "ReiserFS extended attributes" 57 depends on REISERFS_FS 58 help 59 Extended attributes are name:value pairs associated with inodes by 60 the kernel or by users (see the attr(5) manual page, or visit 61 <http://acl.bestbits.at/> for details). 62 63 If unsure, say N. 64 65 config REISERFS_FS_POSIX_ACL 66 bool "ReiserFS POSIX Access Control Lists" 67 depends on REISERFS_FS_XATTR 68 select FS_POSIX_ACL 69 help 70 Posix Access Control Lists (ACLs) support permissions for users and 71 groups beyond the owner/group/world scheme. 72 73 To learn more about Access Control Lists, visit the Posix ACLs for 74 Linux website <http://acl.bestbits.at/>. 75 76 If you don't know what Access Control Lists are, say N 77 78 config REISERFS_FS_SECURITY 79 bool "ReiserFS Security Labels" 80 depends on REISERFS_FS_XATTR 81 help 82 Security labels support alternative access control models 83 implemented by security modules like SELinux.
