Staging: pohmelfs: distributed locking and cache coherency protocol.

POHMELFS utilizes writeback cache, which is built on top of MO(E)SI-like
coherency protocol. This patch includes its implementation and cache
object processing helpers (like allocation and completion callbacks).

POHMELFS uses scalable cached read/write locking. No additional requests
are performed if lock is granted to the filesystem. The same protocol
is used by the server to on-demand flushing of the client's cache (for
example when server wants to update local data).

Staging: pohmelfs: inode operations.

This is the main patch which implements inode operations
(like reading and writing) and superblock processing
(filesystem registration, initial autoconfiguration
with the server like permissions, size of the exported
dir, amount of the objects created and so on).

POHMELFS relies on system's writeback cache mechanism
shown here, as long as cache coherency protocol described
later.

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: rt2860: Ported v1.7.1.1 changes into v1.8.0.0, becoming v1.8.1.1

When RaLink released rt2860 v1.7.0.0, it lacked proper support for both WEP
and WPA/WPA2 encryption. Either was possible, but the module had to be
compiled to support only one or the other, never both.

Since the EeePC was the most common device with this hardware (and these
users were complaining to RaLink that WPA/WPA2 encryption didn't work)
RaLink released a fix as an "eeepc-specific" version of this driver, v1.7.1.1

Unfortunately, when v1.8.0.0 was released, this WPA/WPA2 fix was never
included.

What complicates things further is that RaLink has no interest in
continuing work on this Linux driver for their hardware.

This commit ports the changes introduced in v1.7.1.1 into the v1.8.0.0
release, upgrading the kernel's module to v1.8.1.1

Staging: otus: use USB API functions rather than constants

This set of patches introduces calls to the following set of functions:

usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)

usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK

USB_ENDPOINT_XFER_ISOC

Staging: wlan-ng: block ioctls until card fully initialised

Add a mutex to block ioctls before the card is fully initialised and
only allow one ioctl at a time.
This stops udev trying to load the firmware before to card is fully up.
