604b5bc804 drm/i915: Restore lost glk FBC 16bpp w/a
We lost the FBC 16bpp 512byte stride requirement on glk when
we switched from display version 9 to 10. Restore the w/a to
avoid enabling FBC with a bad stride and thus display garbage.

eef24f1177 drm/i915: Take request reference before arming the watchdog timer
Reference needs to be taken before arming the timer. Luckily, given the

7e9be673cb MIPS: BCM63XX: Use BUG_ON instead of condition followed by BUG.
BUG_ON uses unlikely in if(), it can be optimized at compile time.

Usually, the condition in if() is not satisfied. In my opinion,
this can improve the efficiency of the multi-stage pipeline.

a6efb35019 pwm: Reword docs about pwm_apply_state()
The main issue is that the current documentation talks about the
non-existent function pwm_get_last_applied_state. (This was right in the
context of
https://lore.kernel.org/linux-pwm/20210406073036.26857-1-u.kleine-koenig@pengutronix.de/
but was then missed to adapt when this patch was reduced to a
documentation update.)

While at is also clarify "last applied PWM state" to "PWM state that was
passed to the last invocation of pwm_apply_state()" to better
distinguish to the last actually implemented state and reword to drop a
word repetition.

988cc17552 ALSA: usb-audio: Fix implicit sync clearance at stopping stream
The recent endpoint management change for implicit feedback mode added
a clearance of ep->sync_sink (formerly ep->sync_slave) pointer at
snd_usb_endpoint_stop() to assure no leftover for the feedback from
the already stopped capture stream.  This turned out to cause a
regression, however, when full-duplex streams were running and only a
capture was stopped.  Because of the above clearance of ep->sync_sink
pointer, no more feedback is done, hence the playback will stall.

This patch fixes the ep->sync_sink clearance to be done only after all
endpoints are released, for addressing the regression.

b8d64f8ced smb3: add rasize mount parameter to improve readahead performance

Ceph introduced a mount parameter "rasize" to allow controlling this.
Add mount parameter "rasize" to allow control of amount of readahead

Jiri Olsa says:

====================

hi,
while adding test for pinning the module while there's
trampoline attach to it, I noticed that we don't allow
link detach and following re-attach for trampolines.
Adding that for tracing and lsm programs.

You need to have patch [1] from bpf tree for test module
attach test to pass.

v5 changes:
  - fixed missing hlist_del_init change
  - fixed several ASSERT calls
  - added extra patch for missing ';'
  - added ASSERT macros to lsm test
  - added acks

    - allow ndo operations to configure VF when the PF is ifdown
    - fix the scenario of the VF taking back control of it's MAC address
    - add Hyper-V VF device IDs

3. Support the option to transmit without FCS/CRC.

4. Implement .ndo_features_check() to disable offload when the UDP

MAC address the VF wants to use.  Ultimately the VF will fail when it

dd85fc0ab5 bnxt_en: allow promiscuous mode for trusted VFs
Firmware previously only allowed promiscuous mode for VFs associated with
a default VLAN. It is now possible to enable promiscuous mode for a VF
having no VLAN configured provided that it is trusted. In such cases the
VF will see all packets received by the PF, irrespective of destination
MAC or VLAN.

Note, it is necessary to query firmware at the time of bnxt_promisc_ok()
instead of in bnxt_hwrm_func_qcfg() because the trusted status might be
altered by the PF after the VF has been configured. This check must now
also be deferred because the firmware call sleeps.

driver.

Add a platform data bool to tell us whether to
register an MDIO bus for the device or not, as well
as the corresponding NPE.

We need to drop the memory region request as part of
this since the OF core will request the memory for the
device.

ae68933422 netfilter: ip_tables: pass table pointer via nf_hook_ops
iptable_x modules rely on 'struct net' to contain a pointer to the
table that should be evaluated.

In order to remove these pointers from struct net, pass them via
the 'priv' pointer in a similar fashion as nf_tables passes the
rule data.

To do that, duplicate the nf_hook_info array passed in from the
iptable_x modules, update the ops->priv pointers of the copy to
refer to the table and then change the hookfn implementations to
just pass the 'priv' argument to the traverser.

After this patch, the xt_table pointers can already be removed
from struct net.

However, changes to struct net result in re-compile of the entire
network stack, so do the removal after arptables and ip6tables
have been converted as well.

a4aeafa28c netfilter: xt_nat: pass table to hookfn
This changes how ip(6)table nat passes the ruleset/table to the
evaluation loop.

At the moment, it will fetch the table from struct net.

This change stores the table in the hook_ops 'priv' argument
instead.

This requires to duplicate the hook_ops for each netns, so
they can store the (per-net) xt_table structure.

The dupliated nat hook_ops get stored in net_generic data area.
They are free'd in the namespace exit path.

This is a pre-requisite to remove the xt_table/ruleset pointers
from struct net.

f68772ed67 netfilter: x_tables: remove paranoia tests
No need for these.
There is only one caller, the xtables core, when the table is registered
for the first time with a particular network namespace.

After ->table_init() call, the table is linked into the tables[af] list,
so next call to that function will skip the ->table_init().

20a9df3359 netfilter: iptables: unregister the tables by name
xtables stores the xt_table structs in the struct net.  This isn't
needed anymore, the structures could be passed via the netfilter hook
'private' pointer to the hook functions, which would allow us to remove
those pointers from struct net.

As a first step, reduce the number of accesses to the
net->ipv4.ip6table_{raw,filter,...} pointers.
This allows the tables to get unregistered by name instead of having to
pass the raw address.

The xt_table structure cane looked up by name+address family instead.

This patch is useless as-is (the backends still have the raw pointer
address), but it lowers the bar to remove those.

It also allows to put the 'was table registered in the first place' check
into ip_tables.c rather than have it in each table sub module.

4c95e0728e netfilter: ebtables: remove the 3 ebtables pointers from struct net
ebtables stores the table internal data (what gets passed to the
ebt_do_table() interpreter) in struct net.

nftables keeps the internal interpreter format in pernet lists
and passes it via the netfilter core infrastructure (priv pointer).

Do the same for ebtables: the nf_hook_ops are duplicated via kmemdup,
then the ops->priv pointer is set to the table that is being registered.

After that, the netfilter core passes this table info to the hookfn.

This allows to remove the pointers from struct net.

Same pattern can be applied to ip/ip6/arptables.

de8c12110a netfilter: disable defrag once its no longer needed
When I changed defrag hooks to no longer get registered by default I
intentionally made it so that registration can only be un-done by unloading
the nf_defrag_ipv4/6 module.

In hindsight this was too conservative; there is no reason to keep defrag
on while there is no feature dependency anymore.

Moreover, this won't work if user isn't allowed to remove nf_defrag module.

This adds the disable() functions for both ipv4 and ipv6 and calls them
from conntrack, TPROXY and the xtables socket module.

ipvs isn't converted here, it will behave as before this patch and
will need module removal.

64ff412ad4 hv_netvsc: Make netvsc/VF binding check both MAC and serial number
Currently the netvsc/VF binding logic only checks the PCI serial number.

The Microsoft Azure Network Adapter (MANA) supports multiple net_device
interfaces (each such interface is called a "vPort", and has its unique
MAC address) which are backed by the same VF PCI device, so the binding
logic should check both the MAC address and the PCI serial number.

The change should not break any other existing VF drivers, because
Hyper-V NIC SR-IOV implementation requires the netvsc network
interface and the VF network interface have the same MAC address.
