I suggest to choose another imperative wording for your change description.
Will the tag “Fixes” become helpful for the commit message?

Hi all,
Please help review this new version for the Kenrel 5.9 release.
Now, you may apply the last two qemu-devel patches to the upstream
qemu and try the guest LBR feature with '-cpu host' command line.

The LBR feature would be enabled on the guest if:
- the KVM is enabled and the PMU is enabled and,

- the supported returned value for lbr_fmt from this msr is not zero.

The MSR variable type can be 'unsigned int', which uses less memory than
the longer 'unsigned long'. Fix 'struct x86_pmu' for that. The lbr_nr won't
be a negative number, so make it 'unsigned int' as well.

The LBR records msrs are model specific. The perf subsystem has already
obtained the base addresses of LBR records based on the cpu model.
Therefore, an interface is added to allow callers outside the perf
subsystem to obtain these LBR information. It's useful for hypervisors
to emulate the LBR fe
The Perfmon and Debug Capability MSR named IA32_PERF_CAPABILITIES is
a feature-enumerating MSR, which only enumerates the feature full-width
write (via bit 13) by now which indicates the processor supports IA32_A_PMCx
interface for updating bits 32 and above of IA32_PMCx.
The existence of MSR IA32
The current vPMU only supports Architecture Version 2. According to
Intel SDM "17.4.7 Freezing LBR and Performance Counters on PMI", if
IA32_DEBUGCTL.Freeze_LBR_On_PMI = 1, the LBR is frozen on the virtual
PMI and the KVM would emulate to clear the LBR bit (bit 0) in
IA32_DEBUGCTL. Also guest needs
The bits [0, 5] of the read-only MSR_IA32_PERF_CAPABILITIES tells about
the record format stored in the LBR records. Userspace could expose guest
LBR when host supports LBR and the exactly supported LBR format value is
initialized to the MSR_IA32_PERF_CAPABILITIES and vcpu model is compatible.
Sig
The hypervisor may request the perf subsystem to schedule a time window
to directly access the LBR records msrs for its own use. Normally, it would
create a guest LBR event with callstack mode enabled, which is scheduled
along with other ordinary LBR events on the host but in an exclusive way.
To
The guest first access on the LBR related msrs (including DEBUGCTLMSR and
records msrs) is always interceptible. The KVM handler would create a guest
LBR event which enables the callstack mode and none of hardware counter is
assigned. The host perf would schedule and enable this event as usual but
The vPMU uses GUEST_LBR_IN_USE_IDX (bit 58) in 'pmu->pmc_in_use' to
indicate whether a guest LBR event is still needed by the vcpu. If the
vcpu no longer accesses LBR related registers within a scheduling time
slice, and the enable bit of LBR has been unset, vPMU will treat the
guest LBR event as a
When a guest wants to use the LBR registers, its hypervisor creates a guest
LBR event and let host perf schedules it. The LBR records msrs are
accessible to the guest when its guest LBR event is scheduled on
by the perf subsystem.
Before scheduling this event out, we should avoid host changes on

When the LBR feature is reported by the vmx_get_perf_capabilities(),

open_shroot() invokes kref_get(), which increases the refcount of the
"tcon->crfid" object. When open_shroot() returns not zero, it means the
open operation failed and close_shroot() will not be called to decrement
the refcount of the "tcon->crfid".
The reference counting issue happens in one norm

ttm_bo_vm_fault_reserved() invokes dma_fence_get(), which returns a
reference of the specified dma_fence object to "moving" with increased
refcnt.
When ttm_bo_vm_fault_reserved() returns, local variable "moving" becomes
invalid, so the refcount should be decreased to keep refcount balanced.

In sctp_skb_recv_datagram(), the function fetch a sk_buff object from
the receiving queue to "skb" by calling skb_peek() or __skb_dequeue()
and return its reference to the caller.
However, when calling __skb_dequeue() successfully, the function forgets
to hold a reference count of the "skb" object

uart_shutdown() invokes uart_port_lock(), which returns a reference of
the uart_port object if increases the refcount of the uart_state object
successfully or returns NULL if fails.
However, uart_shutdown() don't take the return value of uart_port_lock()
as the new uart_port object to "uport" and

The main reason is to prevent splice because
