fs/reiserfs/Kconfig v3.0-rc7


Reiserfs support

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.''

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.


Enable reiserfs debug mode

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.


Stats in /proc/fs/reiserfs

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.


ReiserFS extended attributes

Extended attributes are name:value pairs associated with inodes by
the kernel or by users (see the attr(5) manual page, or visit
<http://acl.bestbits.at/> for details).

If unsure, say N.


ReiserFS POSIX Access Control Lists

Posix Access Control Lists (ACLs) support permissions for users and
groups beyond the owner/group/world scheme.

To learn more about Access Control Lists, visit the Posix ACLs for
Linux website <http://acl.bestbits.at/>.

If you don't know what Access Control Lists are, say N


ReiserFS Security Labels

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.
