help
Reiserfs is deprecated and scheduled to be removed from the kernel
in 2025. If you are still using it, please migrate to another
filesystem or tell us your usecase for reiserfs.
Reiserfs stores not just filenames but the files themselves in a
balanced tree. Uses journalling.
Balanced trees are more efficient than traditional file system
architectural foundations.
In general, ReiserFS is as fast as ext2, but is very efficient with
large directories and small files. Additional patches are needed
for NFS and quotas, please see
<https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
It is more easily extended to have features currently found in
database and keyword search systems than block allocation based file
systems are. The next version will be so extended, and will support
plugins consistent with our motto ``It takes more than a license to
make source code open.''
Read <https://reiser4.wiki.kernel.org/index.php/Main_Page>
to learn more about reiserfs.

If you like it, you can pay us to add new features to it that you
need, buy a support contract, or pay us to port it to another OS.
config REISERFS_CHECK
bool "Enable reiserfs debug mode"
depends on REISERFS_FS
help
If you set this to Y, then ReiserFS will perform every check it can
possibly imagine of its internal consistency throughout its
operation. It will also go substantially slower. More than once we
have forgotten that this was on, and then gone despondent over the
latest benchmarks.:-) Use of this option allows our team to go all
out in checking for consistency when debugging without fear of its
effect on end users. If you are on the verge of sending in a bug
report, say Y and you might get a useful error message. Almost
everyone should say N.
config REISERFS_PROC_INFO
bool "Stats in /proc/fs/reiserfs"
depends on REISERFS_FS && PROC_FS
help
Create under /proc/fs/reiserfs a hierarchy of files, displaying
various ReiserFS statistics and internal data at the expense of
making your kernel or module slightly larger (+8 KB). This also
increases the amount of kernel memory required for each mount.
Almost everyone but ReiserFS developers and people fine-tuning
reiserfs or tracing problems should say N.
config REISERFS_FS_XATTR
bool "ReiserFS extended attributes"
depends on REISERFS_FS
help
Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page for details).
If unsure, say N.
config REISERFS_FS_POSIX_ACL
bool "ReiserFS POSIX Access Control Lists"
depends on REISERFS_FS_XATTR
select FS_POSIX_ACL
help
Posix Access Control Lists (ACLs) support permissions for users and
groups beyond the owner/group/world scheme.
If you don't know what Access Control Lists are, say N
config REISERFS_FS_SECURITY
bool "ReiserFS Security Labels"
depends on REISERFS_FS_XATTR
help
Security labels support alternative access control models
implemented by security modules like SELinux. This option
enables an extended attribute handler for file security
labels in the ReiserFS filesystem.
If you are not using a security module that requires using
extended attributes for file security labels, say N.
