Modern TCP stack highly depends on tcp_write_timer() having a small
latency, but current implementation doesn't exactly meet the
expectations.
When a timer fires but finds the socket is owned by the user, it rearms
itself for an additional delay hoping next run will be more
successful.
tcp_write_timer() for example uses a 50ms delay for next try, and it
defeats many attempts to get predictable TCP behavior in term of
latencies.
Use the recently introduced tcp_release_cb(), so that the user owning
the socket will call various handlers right before socket release.
This will permit us to post a followup patch to address the
tcp_tso_should_defer() syndrome (some deferred packets have to wait
RTO timer to be transmitted, while cwnd should allow us to send them
sooner)

The Janz VMOD-ICAN3 hardware has support for one shot packet
transmission. This means that a packet will be attempted to be sent
once, with no automatic retries.
The SocketCAN core has a controller-wide setting for this mode:
CAN_CTRLMODE_ONE_SHOT. The Janz VMOD-ICAN3 hardware supports this flag
on a per-packet level, but the SocketCAN core does not.

If the bus error quota is set to infinite and the host CPU cannot keep
up, the Janz VMOD-ICAN3 firmware will stop responding to control
messages until the controller is reset.
The firmware will automatically stop sending bus error messages when the
quota is reached, and will only resume sending bus error messages when
the quota is re-set to a positive value.
This limitation is worked around by setting the bus error quota to one
message, and then re-setting the quota to one message every time a bus
error message is received. By doing this, the firmware never stops
responding to control messages. The CAN bus can be reset without a
hard-reset of the controller card.

The Janz VMOD-ICAN3 firmware does not support any sort of TX-done
notification or interrupt. The driver previously used the hardware
loopback to attempt to work around this deficiency, but this caused all
sockets to receive all messages, even if CAN_RAW_RECV_OWN_MSGS is off.
Using the new function ican3_cmp_echo_skb(), we can drop the loopback
messages and return the original skbs. This fixes the issues with
CAN_RAW_RECV_OWN_MSGS.
A private skb queue is used to store the echo skbs. This avoids the need
for any index management.
Due to a lack of TX-error interrupts, bus errors are permanently
enabled, and are used as a TX-error notification. This is used to drop
an echo skb when transmission fails. Bus error packets are not generated
if the user has not enabled bus error reporting.

The error and byte counter statistics were being incremented
incorrectly. For example, a TX error would be counted both in tx_errors
and rx_errors.
This corrects the problem so that tx_errors and rx_errors are only
incremented for errors caused by packets sent to the bus. Error packets
generated by the driver are not counted.
The byte counters are only increased for packets which are actually
transmitted or received from the bus. Error packets generated by the
driver are not counted.

We can't guarantee that REQ_DISCARD on dm-mirror zeroes the data even if
the underlying disks support zero on discard. So this patch sets
ti->discard_zeroes_data_unsupported.
For example, if the mirror is in the process of resynchronizing, it may
happen that kcopyd reads a piece of data, then discard is sent on the
same area and then kcopyd writes the piece of data to another leg.
Consequently, the data is not zeroed.
The flag was made available by commit 983c7db347
(dm crypt: always disable discard_zeroes_data).

When process_discard receives a partial discard that doesn't cover a
full block, it sends this discard down to that block. Unfortunately, the
block can be shared and the discard would corrupt the other snapshots
sharing this block.
This patch detects block sharing and ends the discard with success when
sending it to the shared block.
The above change means that if the device supports discard it can't be
guaranteed that a discard request zeroes data. Therefore, we set
ti->discard_zeroes_data_unsupported.

104655fd4d (dm thin: support discards).

This patch fixes a crash when a discard request is sent during mirror
recovery.
Firstly, some background. Generally, the following sequence happens during
mirror synchronization:
- function do_recovery is called
- do_recovery calls dm_rh_recovery_prepare
- dm_rh_recovery_prepare uses a semaphore to limit the number
simultaneously recovered regions (by default the semaphore value is 1,
so only one region at a time is recovered)
- dm_rh_recovery_prepare calls __rh_recovery_prepare,
__rh_recovery_prepare asks the log driver for the next region to
recover. Then, it sets the region state to DM_RH_RECOVERING. If there
are no pending I/Os on this region, the region is added to
quiesced_regions list. If there are pending I/Os, the region is not
added to any list. It is added to the quiesced_regions list later (by
dm_rh_dec function) when all I/Os finish.
- when the region is on quiesced_regions list, there are no I/Os in
flight on this region. The region is popped from the list in
dm_rh_recovery_start function. Then, a kcopyd job is started in the
recover function.
- when the kcopyd job finishes, recovery_complete is called. It calls
dm_rh_recovery_end. dm_rh_recovery_end adds the region to
recovered_regions or failed_recovered_regions list (depending on
whether the copy operation was successful or not).
The above mechanism assumes that if the region is in DM_RH_RECOVERING
state, no new I/Os are started on this region. When I/O is started,
dm_rh_inc_pending is called, which increases reg->pending count. When
I/O is finished, dm_rh_dec is called. It decreases reg->pending count.
If the count is zero and the region was in DM_RH_RECOVERING state,
dm_rh_dec adds it to the quiesced_regions list.
Consequently, if we call dm_rh_inc_pending/dm_rh_dec while the region is
in DM_RH_RECOVERING state, it could be added to quiesced_regions list
multiple times or it could be added to this list when kcopyd is copying
data (it is assumed that the region is not on any list while kcopyd does
its jobs). This results in memory corruption and crash.
There already exist bypasses for REQ_FLUSH requests: REQ_FLUSH requests
do not belong to any region, so they are always added to the sync list
in do_writes. dm_rh_inc_pending does not increase count for REQ_FLUSH
requests. In mirror_end_io, dm_rh_dec is never called for REQ_FLUSH
requests. These bypasses avoid the crash possibility described above.
These bypasses were improperly implemented for REQ_DISCARD when
the mirror target gained discard support in commit
5fc2ffeabb (dm raid1: support discard).
In do_writes, REQ_DISCARD requests is always added to the sync queue and
immediately dispatched (even if the region is in DM_RH_RECOVERING). However,
dm_rh_inc and dm_rh_dec is called for REQ_DISCARD resusts. So it violates the
rule that no I/Os are started on DM_RH_RECOVERING regions, and causes the list
corruption described above.
This patch changes it so that REQ_DISCARD requests follow the same path
as REQ_FLUSH. This avoids the crash.

hid-picolcd and hid-wiimote do not allow any of hidinput, hiddev or hidraw
to claim the device but still want to remain on the bus. Hence, if a
driver uses the raw_event callback but no other listener claimed the
device, we still leave it on the bus as the driver handles everything by
itself. It thus becomes its own listener.
Under some circumstances (eg., hidinput_connect() fails and raw_event set)
a device may be left on the bus even though it requires external
listeners. But then if hidinput_connect() fails there are bigger issues
than a device that is left unhandled. So we can safely use this heuristic
to avoid adding another flag for special devices like hid-picolcd and
hid-wiimote.
This also removes the ugly hack from hid-picolcd as this is no longer
required.

This patch adds support for a second clock to the flexcan driver. On
modern freescale ARM cores like the imx53 and imx6q two clocks ("ipg"
and "per") must be enabled in order to access the CAN core.
In the original driver, the clock was requested without specifying the
connection id, further all mainline ARM archs with flexcan support
(imx28, imx25, imx35) register their flexcan clock without a
connection id, too.
This patch first renames the existing clk variable to clk_ipg and
converts it to devm for easier error handling. The connection id "ipg"
is added to the devm_clk_get() call. Then a second clock "per" is
requested. As all archs don't specify a connection id, both clk_get
return the same clock. This ensures compatibility to existing flexcan
support and adds support for imx53 at the same time.
After this patch hits mainline, the archs may give their existing
flexcan clock the "ipg" connection id and implement a dummy "per"
clock.
This patch has been tested on imx28 (unmodified clk tree) and on imx53
with a seperate "ipg" and "per" clock.

If we drop the breadcrumb request after a batch due to a signal for
example we aim to fix it up at the next opportunity. In this case we
emit a second batchbuffer with no waits upon the first and so no
opportunity to insert the missing request, so we need to emit the
missing flush for coherency. (Note that that invalidating the render
cache is the same as flushing it, so there should have been no
observable corruption.)
Note that beside simply adding the missing flush, avoiding potential
render corruption, this will also fix at least parts of the problem
introduced by some funny interaction of these two commits:

drm/i915: disable flushing_list/gpu_write_list
which essentially disabled the flushing list.
The issue happens when we submit a batch & emit it, but get
interrupted (thanks to the first patch) while trying to emit the
flush. On the next batch we still assume that the full gpu domain
handling is in effect and hence compute the invalidate&flushing
domains. But thanks to the 2nd patch we totally ignore these and only
invalidate all gpu domains, presuming that any required flushes have
been issued already. Which is wrong and eventually results in us
updating the new write_domain values with the computed
pending_write_domain values, which leaves an object with write_domain
== 0 on the gpu_write_list.
As soon as we try to unbind that object, things blow up.
Fix this by emitting the missing flush according to the new
ring->gpu_caches_dirty flag.
Note that this does _not_ fix all the current cases where we end up
with an object on the flushing_list that can't be flushed.

start the training, the monitor keeps telling us to increase the
voltage, then when we reach the maximum we just go back to the start
(because of the "memset" above "voltage_tries = 0"). When we reach
this point, we keep alternating between the maximum and the minimum
voltages until we give up.
The DP spec suggests that we should try the same voltage 5 times
