-config DST
-        tristate "Distributed storage"
-        depends on NET && CRYPTO && SYSFS && BLK_DEV
-        select CONNECTOR
-        ---help---
-        DST is a network block device storage, which can be used to organize
-        exported storage on the remote nodes into the local block device.
-
-        DST works on top of any network media and protocol; it is just a matter
-        of configuration utility to understand the correct addresses. The most
-        common example is TCP over IP, which allows to pass through firewalls and
-        create remote backup storage in a different datacenter. DST requires
-        single port to be enabled on the exporting node and outgoing connections
-        on the local node.
-
-        DST works with in-kernel client and server, which improves performance by
-        eliminating unneded data copies and by not depending on the version
-        of the external IO components. It requires userspace configuration utility
-        though.
-
-        DST uses transaction model, when each store has to be explicitly acked
-        from the remote node to be considered as successfully written. There
-        may be lots of in-flight transactions. When remote host does not ack
-        the transaction it will be resent predefined number of times with specified
-        timeouts between them. All those parameters are configurable. Transactions
-        are marked as failed after all resends complete unsuccessfully; having
-        long enough resend timeout and/or large number of resends allows not to
-        return error to the higher (FS usually) layer in case of short network
-        problems or remote node outages. In case of network RAID setup this means
-        that storage will not degrade until transactions are marked as failed, and
-        thus will not force checksum recalculation and data rebuild. In case of
-        connection failure DST will try to reconnect to the remote node automatically.
-        DST sends ping commands at idle time to detect if remote node is alive.
-
-        Because of transactional model it is possible to use zero-copy sending
-        without worry of data corruption (which in turn could be detected by the
-        strong checksums though).
-
-        DST may fully encrypt the data channel in case of untrusted channel and implement
-        strong checksum of the transferred data. It is possible to configure algorithms
-        and crypto keys; they should match on both sides of the network channel.
-        Crypto processing does not introduce noticeble performance overhead, since DST
-        uses configurable pool of threads to perform crypto processing.
-
-        DST utilizes memory pool model of all its transaction allocations (it is the
-        only additional allocation on the client) and server allocations (bio pools,
-        while pages are allocated from the slab).
-
-        At startup DST performs a simple negotiation with the export node to determine
-        access permissions and size of the exported storage. It can be extended if
-        new parameters should be autonegotiated.
-
-        DST carries block IO flags in the protocol, which allows to transparently implement
-        barriers and sync/flush operations. Those flags are used in the export node where
-        IO against the local storage is performed, which means that sync write will be sync
-        on the remote node too, which in turn improves data integrity and improved resistance
-        to errors and data corruption during power outages or storage damages.
