1# SPDX-License-Identifier: GPL-2.0-only 2config REISERFS_FS 3 tristate "Reiserfs support (deprecated)" 4 select CRC32 5 help 6 Reiserfs is deprecated and scheduled to be removed from the kernel 7 in 2025. If you are still using it, please migrate to another 8 filesystem or tell us your usecase for reiserfs. 9 10 Reiserfs stores not just filenames but the files themselves in a 11 balanced tree. Uses journalling. 12 13 Balanced trees are more efficient than traditional file system 14 architectural foundations. 15 16 In general, ReiserFS is as fast as ext2, but is very efficient with 17 large directories and small files. Additional patches are needed 18 for NFS and quotas, please see 19 <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links. 20 21 It is more easily extended to have features currently found in 22 database and keyword search systems than block allocation based file 23 systems are. The next version will be so extended, and will support 24 plugins consistent with our motto ``It takes more than a license to 25 make source code open.'' 26 27 Read <https://reiser4.wiki.kernel.org/index.php/Main_Page> 28 to learn more about reiserfs. 29 30 Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com. 31 32 If you like it, you can pay us to add new features to it that you 33 need, buy a support contract, or pay us to port it to another OS. 34 35config REISERFS_CHECK 36 bool "Enable reiserfs debug mode" 37 depends on REISERFS_FS 38 help 39 If you set this to Y, then ReiserFS will perform every check it can 40 possibly imagine of its internal consistency throughout its 41 operation. It will also go substantially slower. More than once we 42 have forgotten that this was on, and then gone despondent over the 43 latest benchmarks.:-) Use of this option allows our team to go all 44 out in checking for consistency when debugging without fear of its 45 effect on end users. If you are on the verge of sending in a bug 46 report, say Y and you might get a useful error message. Almost 47 everyone should say N. 48 49config REISERFS_PROC_INFO 50 bool "Stats in /proc/fs/reiserfs" 51 depends on REISERFS_FS && PROC_FS 52 help 53 Create under /proc/fs/reiserfs a hierarchy of files, displaying 54 various ReiserFS statistics and internal data at the expense of 55 making your kernel or module slightly larger (+8 KB). This also 56 increases the amount of kernel memory required for each mount. 57 Almost everyone but ReiserFS developers and people fine-tuning 58 reiserfs or tracing problems should say N. 59 60config REISERFS_FS_XATTR 61 bool "ReiserFS extended attributes" 62 depends on REISERFS_FS 63 help 64 Extended attributes are name:value pairs associated with inodes by 65 the kernel or by users (see the attr(5) manual page for details). 66 67 If unsure, say N. 68 69config REISERFS_FS_POSIX_ACL 70 bool "ReiserFS POSIX Access Control Lists" 71 depends on REISERFS_FS_XATTR 72 select FS_POSIX_ACL 73 help 74 Posix Access Control Lists (ACLs) support permissions for users and 75 groups beyond the owner/group/world scheme. 76 77 If you don't know what Access Control Lists are, say N 78 79config REISERFS_FS_SECURITY 80 bool "ReiserFS Security Labels" 81 depends on REISERFS_FS_XATTR 82 help 83 Security labels support alternative access control models 84 implemented by security modules like SELinux. This option 85 enables an extended attribute handler for file security 86 labels in the ReiserFS filesystem. 87 88 If you are not using a security module that requires using 89 extended attributes for file security labels, say N. 90
