This is a main network processing patch. It includes
both low-level socket machinery, zero-copy sending helpers,
receiving and parsing callbacks and mainly logical
commands handlers.
POHMELFS uses async network approach, when every command
can be separated from its answer and received after some
time after the request during which another lots of commands
can be injected into the network and replies to them received.
With read operation balancing between multiple hosts it is possible
that operations will arrive out of order and this is handled
by the transaction mechanism described partially here.
Having a transaction to guard the set of logically compound operations
allows to send data without thinking about its status and using
zero-copy sending mechanism, since transaction will receive explicit
acks from the servers when they are completed.

Staging: dst: crypto processing.
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.
This patch introduces crypto processing helpers and crypto engine initialization:
glueing with the crypto layer, allocation and initialization of the crypto
processing thread pool, allocation of the cached pages, which are used to temporary
encrypt data into, since it is forbidden to encrypt data in-place, since pages
are used by the higher layers.

Staging: dst: transactions.
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 completed 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).
Transactions are handled in this patch: allocation/freeing/completion,
scanning for stall and to-be-resent transactions and overall management
of the storing tree.

Staging: dst: thread pool.
Kernel currently does not allow to queue work into some entity which
will perform it in the process context and have simple way to extend
number of worker and work with them not as separate objects, but with
pool as a whole. So thread pool model was implemented in the DST.
Thread pool abstraction allows to schedule a work to be performed
on behalf of kernel thread. One does not operate with threads itself,
instead user provides setup and cleanup callbacks for thread pool itself,
and action and cleanup callbacks for each submitted work.
Each worker has private data initialized at creation time and data,
provided by user at scheduling time.
When action is being performed, thread can not be used by other users,
instead they will sleep until there is free thread to pick their work.
Thread pool is used for crypto processing of incoming and outgoing IO
requests to reduce the overall overhead.

Staging: dst: export node.
This patch introduces remote (export) node machinery: initialization
address/port (and other socket parameters), export block device (can be
another DST storage for example or local device like /dev/sda1), local
IO processing engine (BIO state machines, receiving/submitting logic).
Network management for the export node like accepting new client, scheduling
its command processing thread, receiving/sending IO requests, all are placed
here.

This patch contains local node processing engine: network state storage,

Staging: dst: core files.
This patch contains DST core files, which introduce
block layer, connector and sysfs registration glue and main headers.
Connector is used for the configuration of the node (its type, address,
device name and so on). Sysfs provides bits of information about running
devices in the following format:
+/*
+ * DST sysfs tree for device called 'storage':
+ *
+ * /sys/bus/dst/devices/storage/
+ * /sys/bus/dst/devices/storage/type : 192.168.4.80:1025
+ * /sys/bus/dst/devices/storage/size : 800
+ * /sys/bus/dst/devices/storage/name : storage
+ */
DST header contains structure definitions and protocol command description.
