Getting fantastic copy performance with cp --reflink over SMB3.11
using the new FSCTL_DUPLICATE_EXTENTS.
This FSCTL was added in the SMB3.11 dialect (testing was
against REFS file system) so have put it as a 3.11 protocol
specific operation ("vers=3.1.1" on the mount). Tested at
the SMB3 plugfest in Redmond.
It depends on the new FS Attribute (BLOCK_REFCOUNTING) which
is used to advertise support for the ability to do this ioctl
(if you can support multiple files pointing to the same block
than this refcounting ability or equivalent is needed to
support the new reflink-like duplicate extent SMB3 ioctl.

Intel Wired LAN Driver Updates 2015-06-26
This series contains fixes for igb, e1000e and i40evf.
Todd disables IPv6 extension header processing due to a hardware errata
and bumps the driver version.
Yanir provides six fixes for e1000e. First is a fix for a locking issue
where we were not always taking the pci_bus_sem semaphore all the time
when calling pci_disable_link_state_locked(), so fix the code to only call
pci_disable_link_state_locked() when the semaphore has been acquired,
otherwise call pci_disable_link_state(). A previous fix for i219 where
the hardware prevented ULP entry caused EEE in Sx not the be enabled, so
modify the code flow that allows both ULP and EEE in Sx. Fix an issue
when running 10/100 full duplex on i219 where CRC errors were occurring
by increasing the IPG from 8 to 0xC as per the hardware developers.
Fix a data corruption issue found on some platforms by increasing the
minimum gap between the PHY FIFO read and write pointers. Fix i219,
which does not require the K1 workaround for LPT devices.
Mitch provides a i40evf fix for a panic when changing MTU. Down was
requesting queue disables, but then exited immediately without waiting
for the queues to actually be disabled. This could allow any function
called after i40evf_down() to run immediately, including i40evf_up(),
and causes a memory leak. Fixed the issue by removing the whole
reinit_locked function which allows for the driver to handle the state
changes by requesting reset from the periodic timer. The second fix
resolves an issue where RSS was being configured as though it is using
the maximum number of queue. This can cause the device to drop a lot
of receive traffic, as the packets get assigned to non-functional queues.
This is resolved by only configuring RSS with the number of active queues.

Not all silicon implementations of the Freescale FEC hardware module
have the RACC (Receive Accelerator Function) register, so we should not
be trying to access it on those that don't. Currently none of the ColdFire
based parts with a FEC have it.
Support for RACC was introduced by commit 4c09eed9 ("net: fec: Enable imx6
enet checksum acceleration"). A fix was introduced in commit d1391930
("net: fec: Fix build for MCF5272") that disables its use on the ColdFire
M5272 part, but it doesn't fix the general case of other ColdFire parts.
To fix we create a quirk flag, FEC_QUIRK_HAS_RACC, and check it before
working with the RACC register.

In commit 1f66d161ab
("tipc: introduce starvation free send algorithm")
we introduced a counter per priority level for buffers
in the link backlog queue. We also introduced a new
function tipc_link_purge_backlog(), to reset these
counters to zero when the link is reset.
Unfortunately, we missed to call this function when
the broadcast link is reset, with the result that the
values of these counters might be permanently skewed
when new nodes are attached. This may in the worst case
lead to permananent, but spurious, broadcast link
congestion, where no broadcast packets can be sent at
all.
We fix this bug with this commit.

workqueue: Create low-level unbound workqueues cpumask
workqueue: split apply_workqueue_attrs() into 3 stages
Pull cgroup updates from Tejun Heo:
- threadgroup_lock got reorganized so that its users can pick the
actual locking mechanism to use. Its only user - cgroups - is
updated to use a percpu_rwsem instead of per-process rwsem.
This makes things a bit lighter on hot paths and allows cgroups to
perform and fail multi-task (a process) migrations atomically.
Multi-task migrations are used in several places including the
unified hierarchy.
- Delegation rule and documentation added to unified hierarchy. This
will likely be the last interface update from the cgroup core side
for unified hierarchy before lifting the devel mask.
- Some groundwork for the pids controller which is scheduled to be
merged in the coming devel cycle.
