33 Stores not just filenames but the files themselves in a balanced

35
36 Balanced trees are more efficient than traditional file system
37 architectural foundations.
38
39 In general, ReiserFS is as fast as ext2, but is very efficient with
40 large directories and small files. Additional patches are needed
41 for NFS and quotas, please see <http://www.namesys.com/> for links.
42
43 It is more easily extended to have features currently found in
44 database and keyword search systems than block allocation based file
45 systems are. The next version will be so extended, and will support
46 plugins consistent with our motto ``It takes more than a license to
47 make source code open.''

638 renaming is possible. Note only non-resident files can be written to

640 be written to.

642 While we cannot guarantee that it will not damage any data, we have
643 so far not received a single report where the driver would have
644 damaged someones data so we assume it is perfectly safe to use.

1494 help
1495 Enabling this will make smbfs use nls translations by default. You
1496 need to specify the local charset (CONFIG_NLS_DEFAULT) in the nls
1497 settings and you need to give the default nls for the SMB server as
1498 CONFIG_SMB_NLS_REMOTE.
1499
1500 The nls settings can be changed at mount time, if your smbmount
1501 supports that, using the codepage and iocharset parameters.
1502
1503 smbmount from samba 2.2.0 or later supports this.

1510 This setting allows you to specify a default value for which
1511 codepage the server uses. If this field is left blank no
1512 translations will be done by default. The local codepage/charset
1513 default to CONFIG_NLS_DEFAULT.

1525 help
1526 NCP (NetWare Core Protocol) is a protocol that runs over IPX and is
1527 used by Novell NetWare clients to talk to file servers. It is to
1528 IPX what NFS is to TCP/IP, if that helps. Saying Y here allows you
1529 to mount NetWare file server volumes and to access them just like
1530 any other Unix directory. For details, please read the file
1531 <file:Documentation/filesystems/ncpfs.txt> in the kernel source and
1532 the IPX-HOWTO from <http://www.tldp.org/docs.html#howto>.
1533
1534 You do not have to say Y here if you want your Linux box to act as a
1535 file *server* for Novell NetWare clients.

1537 General information about how to connect Linux, Windows machines and
1538 Macs is on the WWW at <http://www.eats.com/linux_mac_win.html>.

1547 depends on INET
1548 help
1549 Coda is an advanced network file system, similar to NFS in that it
1550 enables you to mount file systems of a remote server and access them
1551 with regular Unix commands as if they were sitting on your hard
1552 disk. Coda has several advantages over NFS: support for
1553 disconnected operation (e.g. for laptops), read/write server
1554 replication, security model for authentication and encryption,
1555 persistent client caches and write back caching.
1556
1557 If you say Y here, your Linux box will be able to act as a Coda
1558 *client*. You will need user level code as well, both for the
1559 client and server. Servers are currently user level, i.e. they need
1560 no kernel support. Please read
1561 <file:Documentation/filesystems/coda.txt> and check out the Coda
1562 home page <http://www.coda.cs.cmu.edu/>.
1563
1564 To compile the coda client support as a module, choose M here: the
1565 module will be called coda.
