|
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.

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

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.
