The current code unmaps the DMA mapping created for rx skb_buff's by
using the data_size as the the mapping size. This is wrong since the
correct size to specify should match the size used to create the mapping.

br_stp_rcv() is reached by non-rx_handler path. That means there is no
guarantee that dev is bridge port and therefore simple NULL check of
->rx_handler_data is not enough. There is need to check if dev is really
bridge port and since only rcu read lock is held here, do it by checking
->rx_handler pointer.
Note that synchronize_net() in netdev_rx_handler_unregister() ensures
this approach as valid.
Introduced originally by:
commit f350a0a873
"bridge: use rx_handler_data pointer to store net_bridge_port pointer"
Fixed but not in the best way by:
commit b5ed54e94d
"bridge: fix RCU races with bridge port"

Some network drivers use dev_kfree_skb_any() and dev_kfree_skb_irq()
helpers to free skbs, both for dropped packets and TX completed ones.
We need to separate the two causes to get better diagnostics
given by dropwatch or "perf record -e skb:kfree_skb"
This patch provides two new helpers, dev_consume_skb_any() and
dev_consume_skb_irq() to be used for consumed skbs.
__dev_kfree_skb_irq() is slightly optimized to remove one
atomic_dec_and_test() in fast path, and use this_cpu_{r|w} accessors.

cgroup_create() currently does the followings.
1. alloc cgroup
2. alloc css's
3. create the directory and commit to cgroup creation
4. online css's
5. create cgroup and css files
The sequence performs allocations before other operations but it
doesn't buy anything because each of the above steps may fail and
should be unrollable. Reorganize the sequence such that cgroup
operations are done before css operations.
1. alloc cgroup
2. create the directory and files and commit to cgroup creation
3. alloc css's
4. create files for and online css's
This simplifies the code a bit and enables further simplification and
separating out css creation from cgroup creation which is necessary
for the planned unified hierarchy where css's will be created and
destroyed dynamically across the lifetime of a cgroup.

We want to use for_each_subsys() in cgroupfs_root handling where only
cgroup_root_mutex is held. The only way cgroup_subsys[] can change is
through module load/unload, make cgroup_[un]load_subsys() grab
cgroup_root_mutex too and update the lockdep annotation in
for_each_subsys() to allow either cgroup_mutex or cgroup_root_mutex.
* Lockdep annotation is moved from inner 'if' condition to outer 'for'
init caluse. There's no reason to execute the assertion every loop.
* Loop index @i is renamed to @ssid. Indices iterating through subsys
will be [re]named to @ssid gradually.

Currently, all css iterations and css_from_dir() require RCU read lock
whether the caller is holding cgroup_mutex or not, which is
unnecessarily restrictive. They are all safe to use under
cgroup_mutex without holding RCU read lock.
Factor out cgroup_assert_mutex_or_rcu_locked() from css_from_id() and
apply it to all css iteration functions and css_from_dir().
v2: cgroup_assert_mutex_or_rcu_locked() definition doesn't need to be
inside CONFIG_PROVE_RCU ifdef as rcu_lockdep_assert() is always
defined and conditionalized. Move it outside of the ifdef block.

This patch moves reference bumping inside online_css() loop, clears
css_ar[] as css's are brought online successfully, and updates
err_destroy path so that either a css is fully online and destroyed by
cgroup_destroy_locked() or the error path frees it. This creates a
duplicate css free logic in the error path but it will be cleaned up
soon.
v2: Li pointed out that cgroup_destroy_locked() would do NULL-deref if
invoked with a cgroup which doesn't have all css's populated.

In xfs_qm_scall_trunc_qfiles(), we ignore the error if failed to remove
the users quota metadata and proceed to remove groups and projects if
they are being there. However, in user space, the remove operation will
break and return if failed to remove any kind of quota.
Also for v5 super block, we can enabled both group and project quota at
the same time, in this case the current error handling will cover the
group error with projects but they might failed due to different reasons.
It seems we'd better the error handling consistent to the user space and
don't trying to remove another kind of quota metadata if the previous

in sync with hardware updates.
Shannon provides the majority of i40e patches, with 7. First patch
clears the admin queue head and tail registers during admin queue
shutdown. Then simplifies the admin queue head-tail-len setups to
use more virtual registers. Provides several patches to cleanup
and fix driver load and reset procedures to make more robust. Lastly,
provides an ethtool test for interrupts using the software interrupt.
Mitch provides some i40e patches which fixes up VF code in the PF
driver, specifically the number of vectors per VF are reported by the
hardware does not include vector 0, so we need to account for this
when checking. In addition, cleans up debugging messages.
Kamil provides an i40e patch to fix the diagnostics test by restricting
the diagnostic test length.
