INTEL_GET_VENDOR_VERB is defined twice identically.
Let's remove a superfluous line.

The fix for the racy writes and ioctls to sequencer widened the
application of client->ioctl_mutex to the whole write loop. Although
it does unlock/relock for the lengthy operation like the event dup,
the loop keeps the ioctl_mutex for the whole time in other
situations. This may take quite long time if the user-space would
give a huge buffer, and this is a likely cause of some weird behavior
spotted by syzcaller fuzzer.
This patch puts a simple workaround, just adding a mutex break in the
loop when a large number of events have been processed. This
shouldn't hit any performance drop because the threshold is set high
enough for usual operations.

RHBZ: 1722704
In low memory situations the various SMB2_*_init() functions can fail
to allocate a request PDU and thus leave the request iovector as NULL.
If we don't check the return code for failure we end up calling
smb2_set_next_command() with a NULL iovector causing a crash when it tries
to dereference it.

When directories are used as prerequisites in Makefiles, they can cause
a lot of unnecessary rebuilds, because a directory is considered changed
whenever a file in this directory is added, removed or modified.
If the only thing a target is interested in is the existence of the
directory it depends on, which is the case for selftests/bpf, this
directory should be specified as an order-only prerequisite: it would
still be created in case it does not exist, but it would not trigger a

Andrii Nakryiko says:
====================
BTF size resolution logic isn't always resolving type size correctly, leading
to erroneous map creation failures due to value size mismatch.
This patch set:
1. fixes the issue (patch #1);
2. adds tests for trickier cases (patch #2);
3. and converts few test cases utilizing BTF-defined maps, that previously
couldn't use typedef'ed arrays due to kernel bug (patch #3).

BTF verifier has a size resolution bug which in some circumstances leads to
invalid size resolution for, e.g., TYPEDEF modifier. This happens if we have
[1] PTR -> [2] TYPEDEF -> [3] ARRAY, in which case due to being in pointer
context ARRAY size won't be resolved (because for pointer it doesn't matter, so
it's a sink in pointer context), but it will be permanently remembered as zero
for TYPEDEF and TYPEDEF will be marked as RESOLVED. Eventually ARRAY size will
be resolved correctly, but TYPEDEF resolved_size won't be updated anymore.
This, subsequently, will lead to erroneous map creation failure, if that
TYPEDEF is specified as either key or value, as key_size/value_size won't
correspond to resolved size of TYPEDEF (kernel will believe it's zero).
Note, that if BTF was ordered as [1] ARRAY <- [2] TYPEDEF <- [3] PTR, this
won't be a problem, as by the time we get to TYPEDEF, ARRAY's size is already
calculated and stored.
This bug manifests itself in rejecting BTF-defined maps that use array
typedef as a value type:
typedef int array_t[16];
struct {
__uint(type, BPF_MAP_TYPE_ARRAY);
__type(value, array_t); /* i.e., array_t *value; */
} test_map SEC(".maps");
The fix consists on not relying on modifier's resolved_size and instead using
modifier's resolved_id (type ID for "concrete" type to which modifier
eventually resolves) and doing size determination for that resolved type. This
allow to preserve existing "early DFS termination" logic for PTR or
STRUCT_OR_ARRAY contexts, but still do correct size determination for modifier
types.

Recently, fl_flow_key->indev_ifindex int field was refactored into
flow_dissector_key_meta field. With this, flower classifier also sets
FLOW_DISSECTOR_KEY_META flow dissector key. However, mlx5 flower dissector
validation code rejects filters that use flow dissector keys that are not
supported. Add FLOW_DISSECTOR_KEY_META to the list of allowed dissector
keys in __parse_cls_flower() to prevent following error when offloading
flower classifier to mlx5:

Currently, tunnel attributes are parsed and inner header matching is used
only when flow dissector specifies match on some of the supported
encapsulation fields. When user tries to offload tc filter that doesn't
match any encapsulation fields on tunnel device, mlx5 tc layer incorrectly
sets to match packet header keys on encap header (outer header) and
firmware rejects the rule with syndrome 0x7e1579 when creating new flow
group.
Change __parse_cls_flower() to determine whether tunnel is used based on
fitler_dev tunnel info, instead of determining it indirectly by checking
flow dissector enc keys.

As reported by Maxime at
https://bugzilla.kernel.org/show_bug.cgi?id=204175:
In vmx/nested.c::get_vmx_mem_address(), when the guest runs in long mode,
the base address of the memory operand is computed with a simple:
*ret = s.base + off;
This is incorrect, the base applies only to FS and GS, not to the others.
Because of that, if the guest uses a VMX instruction based on DS and has
a DS.base that is non-zero, KVM wrongfully adds the base to the
resulting address.

Since commit ed194d136769 ("usb: core: remove local_irq_save() around
->complete() handler") the handler rt2x00usb_interrupt_rxdone() is
not running with interrupts disabled anymore. So this completion handler
is not guaranteed to run completely before workqueue processing starts
for the same queue entry.
Be sure to set all other flags in the entry correctly before marking
this entry ready for workqueue processing. This way we cannot miss error
conditions that need to be signalled from the completion handler to the
worker thread.
Note that rt2x00usb_work_rxdone() processes all available entries, not
only such for which queue_work() was called.
This patch is similar to what commit df71c9cfceea ("rt2x00: fix order
of entry flags modification") did for TX processing.
This fixes a regression on a RT5370 based wifi stick in AP mode, which
suddenly stopped data transmission after some period of heavy load. Also
stopping the hanging hostapd resulted in the error message "ieee80211
phy0: rt2x00queue_flush_queue: Warning - Queue 14 failed to flush".
Other operation modes are probably affected as well, this just was
the used testcase.

On a latest Lenovo laptop, the trackpoint and 3 buttons below it
don't work at all, when we move the trackpoint or press those 3
buttons, the kernel will print out:
"Rejected trackstick packet from non DualPoint device"
This device is identified as an alps touchpad but the packet has
trackpoint format, so the alps.c drops the packet and prints out
the message above.
According to XiaoXiao's explanation, this device is named cs19 and
is trackpoint-only device, its firmware is only for trackpoint, it
is independent of touchpad and is a device completely different from
DualPoint ones.
To drive this device with mininal changes to the existing driver, we
just let the alps driver not handle this device, then the trackpoint.c
will be the driver of this device if the trackpoint driver is enabled.
(if not, this device will fallback to a bare PS/2 device)
With the trackpoint.c, this trackpoint and 3 buttons all work well,
they have all features that the trackpoint should have, like
scrolling-screen, drag-and-drop and frame-selection.
