If a call to kobject_init_and_add() fails we must call kobject_put()
otherwise we leak memory.
Function gfs2_sys_fs_add always calls kobject_init_and_add() which
always calls kobject_init().
It is safe to leave object destruction up to the kobject release
function and never free it manually.
Remove call to kfree() and always call kobject_put() in the error path.

Appended DTB support is mostly intended to be used on legacy systems,
but it is a valid feature that can be enabled for generic platform,
which currently doesn't support it - if selected, the appended DTB will
be ignored by the platform startup code.
During kernel startup, the appended DTB's location is stored in
fw_passed_dtb if the init code finds what appears to be a valid DTB.
Otherwise (if a0 == -2), a1 is stored in fw_passed_dtb, so either way it
will always point to either a user-passed DTB or built-in DTB.

The driver currently sets register 0xfb (Low Refresh Rate) based on the
value of mode->vrefresh. Firstly, this field is specified to be in Hz,
but the magic numbers used by the code are Hz * 1000. This essentially
leads to the low refresh rate always being set to 0x01, since the
vrefresh value will always be less than 24000. Fix the magic numbers to
be in Hz.
Secondly, according to the comment in drm_modes.h, the field is not
supposed to be used in a functional way anyway. Instead, use the helper
function drm_mode_vrefresh().

When a function falls through to the next function due to a compiler
bug, objtool prints some obscure warnings. For example:
drivers/regulator/core.o: warning: objtool: regulator_count_voltages()+0x95: return with modified stack frame
drivers/regulator/core.o: warning: objtool: regulator_count_voltages()+0x0: stack state mismatch: cfa1=7+32 cfa2=7+8
Instead it should be printing:
drivers/regulator/core.o: warning: objtool: regulator_supply_is_couple() falls through to next function regulator_count_voltages()
This used to work, but was broken by the following commit:
13810435b9a7 ("objtool: Support GCC 8's cold subfunctions")
The padding nops at the end of a function aren't actually part of the
function, as defined by the symbol table. So the 'func' variable in
validate_branch() is getting cleared to NULL when a padding nop is
encountered, breaking the fallthrough detection.
If the current instruction doesn't have a function associated with it,
just consider it to be part of the previously detected function by not
overwriting the previous value of 'func'.

The ignore flag is set on fake jumps in order to keep
add_jump_destinations() from setting their jump_dest, since it already
got set when the fake jump was created.
But using the ignore flag is a bit of a hack. It's normally used to
skip validation of an instruction, which doesn't really make sense for
fake jumps.
Also, after the next patch, using the ignore flag for fake jumps can
trigger a false "why am I validating an ignored function?" warning.
Instead just add an explicit check in add_jump_destinations() to skip
fake jumps.

There's currently a problem with toggling arp_validate on and off with an
active-backup bond. At the moment, you can start up a bond, like so:
modprobe bonding mode=1 arp_interval=100 arp_validate=0 arp_ip_targets=192.168.1.1
ip link set bond0 down
echo "ens4f0" > /sys/class/net/bond0/bonding/slaves
echo "ens4f1" > /sys/class/net/bond0/bonding/slaves
ip link set bond0 up
ip addr add 192.168.1.2/24 dev bond0
Pings to 192.168.1.1 work just fine. Now turn on arp_validate:
echo 1 > /sys/class/net/bond0/bonding/arp_validate
Pings to 192.168.1.1 continue to work just fine. Now when you go to turn
arp_validate off again, the link falls flat on it's face:
echo 0 > /sys/class/net/bond0/bonding/arp_validate
dmesg
...
[133191.911987] bond0: Setting arp_validate to none (0)
[133194.257793] bond0: bond_should_notify_peers: slave ens4f0
[133194.258031] bond0: link status definitely down for interface ens4f0, disabling it
[133194.259000] bond0: making interface ens4f1 the new active one
[133197.330130] bond0: link status definitely down for interface ens4f1, disabling it
[133197.331191] bond0: now running without any active interface!
The problem lies in bond_options.c, where passing in arp_validate=0
results in bond->recv_probe getting set to NULL. This flies directly in
the face of commit 3fe68df97c7f, which says we need to set recv_probe =
bond_arp_recv, even if we're not using arp_validate. Said commit fixed
this in bond_option_arp_interval_set, but missed that we can get to that
same state in bond_option_arp_validate_set as well.
One solution would be to universally set recv_probe = bond_arp_recv here
as well, but I don't think bond_option_arp_validate_set has any business
touching recv_probe at all, and that should be left to the arp_interval
code, so we can just make things much tidier here.

The following bpf workflow breaks when it can't find the test_verifier:

When punting to workers the SQE gets copied after the initial try.
There is a race condition between reading SQE data for the initial try
and copying it for punting it to the workers.
For example io_rw_done calls kiocb->ki_complete even if it was prepared
for IORING_OP_FSYNC (and would be NULL).
The easiest solution for now is to alway prepare again in the worker.
req->file is safe to prepare though as long as it is checked before use.

In the past, before adding f41725bb ("nvme-rdma: Use mr pool") commit,
we needed a reference on the ib_device as long as the tagset
was alive, as the MRs in the request structures needed a valid ib_device.
Now, we allocate/deallocate MR pool per QP and consume on demand.
Also remove nvme_rdma_free_tagset function and use blk_mq_free_tag_set
instead, as it unneeded anymore.
This commit also fixes a memory leakage and possible segmentation fault.
When configuring the system with NIC teaming (aka bonding), we use 1
network interface to create an HA connection to the target side. In case
one connection breaks down, nvme-rdma driver will get notification from
rdma-cm layer that underlying address was change and will start error
recovery process. During this process, we'll reconnect to the target
via the second interface in the bond without destroying the tagset.
This will cause a leakage of the initial rdma device (ndev) and miscount
in the reference count of the new created rdma device (new ndev). In
the final destruction (or in another error flow), we'll get a warning
dump from the ib_dealloc_pd that we still have inflight MR's related to
that pd. This happens becasue of the miscount of the reference tag of
the rdma device and causing access violation to it's elements (some
queues are not destroyed yet).

Currently there is an underlying assumption that i915_request_unsubmit()
is synchronous wrt the GPU -- that is the request is no longer in flight
as we remove it. In the near future that may change, and this may upset
our signaling as we can process an interrupt for that request while it
is no longer in flight.
CPU0 CPU1
intel_engine_breadcrumbs_irq
(queue request completion)
i915_request_cancel_signaling
... ...
i915_request_enable_signaling
dma_fence_signal
Hence in the time it took us to drop the lock to signal the request, a
preemption event may have occurred and re-queued the request. In the
process, that request would have seen I915_FENCE_FLAG_SIGNAL clear and
so reused the rq->signal_link that was in use on CPU0, leading to bad
pointer chasing in intel_engine_breadcrumbs_irq.
A related issue was that if someone started listening for a signal on a
completed but no longer in-flight request, we missed the opportunity to
immediately signal that request.
Furthermore, as intel_contexts may be immediately released during
request retirement, in order to be entirely sure that
intel_engine_breadcrumbs_irq may no longer dereference the intel_context
(ce->signals and ce->signal_link), we must wait for irq spinlock.
In order to prevent the race, we use a bit in the fence.flags to signal
the transfer onto the signal list inside intel_engine_breadcrumbs_irq.
For simplicity, we use the DMA_FENCE_FLAG_SIGNALED_BIT as it then
quickly signals to any outside observer that the fence is indeed signaled.

v3: And the test_and_set_bit()

On HSW the pipe A panel fitter lives inside the display power well,
and the input MUX for the EDP transcoder needs to be configured
appropriately to route the data through the power well as needed.
Changing the MUX setting is not allowed while the pipe is active,
so we need to force a full modeset whenever we need to change it.
Currently we may end up doing a fastset which won't change the
MUX settings, but it will drop the power well reference, and that
kills the pipe.

On many (all?) the Gemini Lake systems we work with, there is frequent
momentary graphical corruption at the top of the screen, and it seems
that disabling framebuffer compression can avoid this.
The ticket was reported 6 months ago and has already affected a
