1# SPDX-License-Identifier: GPL-2.0-only2config REISERFS_FS3 tristate "Reiserfs support (deprecated)"4 select BUFFER_HEAD5 select CRC326 select LEGACY_DIRECT_IO7 help8 Reiserfs is deprecated and scheduled to be removed from the kernel9 in 2025. If you are still using it, please migrate to another10 filesystem or tell us your usecase for reiserfs.11 12 Reiserfs stores not just filenames but the files themselves in a13 balanced tree. Uses journalling.14 15 Balanced trees are more efficient than traditional file system16 architectural foundations.17 18 In general, ReiserFS is as fast as ext2, but is very efficient with19 large directories and small files. Additional patches are needed20 for NFS and quotas, please see 21 <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.22 23 It is more easily extended to have features currently found in24 database and keyword search systems than block allocation based file25 systems are. The next version will be so extended, and will support26 plugins consistent with our motto ``It takes more than a license to27 make source code open.''28 29 Read <https://reiser4.wiki.kernel.org/index.php/Main_Page> 30 to learn more about reiserfs.31 32 Sponsored by Threshold Networks, Emusic.com, and Bigstorage.com.33 34 If you like it, you can pay us to add new features to it that you35 need, buy a support contract, or pay us to port it to another OS.36 37config REISERFS_CHECK38 bool "Enable reiserfs debug mode"39 depends on REISERFS_FS40 help41 If you set this to Y, then ReiserFS will perform every check it can42 possibly imagine of its internal consistency throughout its43 operation. It will also go substantially slower. More than once we44 have forgotten that this was on, and then gone despondent over the45 latest benchmarks.:-) Use of this option allows our team to go all46 out in checking for consistency when debugging without fear of its47 effect on end users. If you are on the verge of sending in a bug48 report, say Y and you might get a useful error message. Almost49 everyone should say N.50 51config REISERFS_PROC_INFO52 bool "Stats in /proc/fs/reiserfs"53 depends on REISERFS_FS && PROC_FS54 help55 Create under /proc/fs/reiserfs a hierarchy of files, displaying56 various ReiserFS statistics and internal data at the expense of57 making your kernel or module slightly larger (+8 KB). This also58 increases the amount of kernel memory required for each mount.59 Almost everyone but ReiserFS developers and people fine-tuning60 reiserfs or tracing problems should say N.61 62config REISERFS_FS_XATTR63 bool "ReiserFS extended attributes"64 depends on REISERFS_FS65 help66 Extended attributes are name:value pairs associated with inodes by67 the kernel or by users (see the attr(5) manual page for details).68 69 If unsure, say N.70 71config REISERFS_FS_POSIX_ACL72 bool "ReiserFS POSIX Access Control Lists"73 depends on REISERFS_FS_XATTR74 select FS_POSIX_ACL75 help76 Posix Access Control Lists (ACLs) support permissions for users and77 groups beyond the owner/group/world scheme.78 79 If you don't know what Access Control Lists are, say N80 81config REISERFS_FS_SECURITY82 bool "ReiserFS Security Labels"83 depends on REISERFS_FS_XATTR84 help85 Security labels support alternative access control models86 implemented by security modules like SELinux. This option87 enables an extended attribute handler for file security88 labels in the ReiserFS filesystem.89 90 If you are not using a security module that requires using91 extended attributes for file security labels, say N.92
