The origin bio carries blk-cgroup information which could be set from
foreground(task_css(css) - wbc->wb->blkcg_css), so the blkcg won't
control buffer io since commit ca522482e3 ("dm: pass NULL bdev to
bio_alloc_clone"). The synchronous io is still under control by blkcg,
because 'bio->bi_blkg' is set by io submitting task which has been added
into 'cgroup.procs'.
Fix it by using bio_clone_blkg_association when submitting a cloned bio.

Drop KVM's filtering of GUEST_INTR_STATUS when generating the shadow VMCS
bitmap now that KVM drops GUEST_INTR_STATUS from the set of supported
vmcs12 fields if the field isn't supported by hardware, and initialization
of the shadow VMCS fields omits unsupported vmcs12 fields.
Note, there is technically a small functional change here, as the vmcs12
filtering only requires support for Virtual Interrupt Delivery, whereas
the shadow VMCS code being removed required "full" APICv support, i.e.
required Virtual Interrupt Delivery *and* APIC Register Virtualizaton *and*
Posted Interrupt support.
Opportunistically tweak the comment to more precisely explain why the
PML and VMX preemption timer fields need to be explicitly checked.

Disallow access (VMREAD/VMWRITE), both emulated and via a shadow VMCS, to
VMCS fields that the loaded incarnation of KVM doesn't support, e.g. due
to lack of hardware support, as a middle ground between allowing access to
any vmcs12 field defined by KVM (current behavior) and gating access based
on the userspace-defined vCPU model (the most functionally correct, but
very costly, implementation).
Disallowing access to unsupported fields helps a tiny bit in terms of
closing the virtualization hole (see below), but the main motivation is to
avoid having to weed out unsupported fields when synchronizing between
vmcs12 and a shadow VMCS. Because shadow VMCS accesses are done via
VMREAD and VMWRITE, KVM _must_ filter out unsupported fields (or eat
VMREAD/VMWRITE failures), and filtering out just shadow VMCS fields is
about the same amount of effort, and arguably much more confusing.
As a bonus, this also fixes a KVM-Unit-Test failure bug when running on
_hardware_ without support for TSC Scaling, which fails with the same
signature as the bug fixed by commit ba1f82456b ("KVM: nVMX: Dynamically
compute max VMCS index for vmcs12"):
FAIL: VMX_VMCS_ENUM.MAX_INDEX expected: 19, actual: 17
Dynamically computing the max VMCS index only resolved the issue where KVM
was hardcoding max index, but for CPUs with TSC Scaling, that was "good
enough".

Trying to change the state of a glock may result in a "conversion
deadlock" error, indicating that the requested state transition would
cause a deadlock. In this case, we unlock and retry the state change.
It makes no sense to try canceling those unlock requests, but the
current code is not aware of that.
In addition, if a locking request is canceled shortly after it is made,
the cancelation request can currently overtake the locking request.
This may result in deadlocks.
Fix both of these bugs by repurposing the GLF_PENDING_REPLY flag into a
GLF_MAY_CANCEL flag which is set only when the current locking request
can be canceled. When trying to cancel a locking request in
gfs2_glock_dq(), wait for this flag to be set.

("gfs2: Use async glocks for rename") mentioned that retries were needed
but never implemented them, causing operations to fail with -ESTALE

Also makes the waiting interruptible.
In addition, the timeouts used were too high for situations in which
timing out is a rare but expected scenario. Switch to shorter timeouts

of that holder (GLF_LOCK not set), the dequeuing takes place in

waking up waiters. Fix that.
This bug prevents the same holder from being enqueued later (gfs2_glock_nq())

doesn't currently use this pattern, but this will change in the next

ib_uverbs_post_send() uses cmd.wqe_size from userspace without any
validation before passing it to kmalloc() and using the allocated
buffer as struct ib_uverbs_send_wr.
If a user provides a small wqe_size value (e.g., 1), kmalloc() will
succeed, but subsequent accesses to user_wr->opcode, user_wr->num_sge,
and other fields will read beyond the allocated buffer, resulting in
an out-of-bounds read from kernel heap memory. This could potentially
leak sensitive kernel information to userspace.
Additionally, providing an excessively large wqe_size can trigger a
WARNING in the memory allocation path, as reported by syzkaller.
This is inconsistent with ib_uverbs_unmarshall_recv() which properly
validates that wqe_size >= sizeof(struct ib_uverbs_recv_wr) before
proceeding.
Add the same validation for ib_uverbs_post_send() to ensure wqe_size
is at least sizeof(struct ib_uverbs_send_wr).

Fix by aligning n_voltages with the hardware register widths per the P1

- BUCK: 255 (was 254), allows selectors 0-254, selector 255 is reserved
- LDO: 128 (was 117), allows selectors 0-127, selectors 0-10 are for

This enables the full voltage range supported by the hardware.
