checkAvailableCounters caches per-pool counter availability under the pool name alone: availableCounters and consumedCounters are keyed by pool.PoolID.Pool. A pool is identified by its driver and name together, and the allocator keys its pool map by PoolID. When two drivers publish a pool with the same name on the same node and both consume counters, the name-only key collides: the second pool's devices are evaluated against the first driver's cached counter set definition and aggregate consumption instead of their own, so a device can be incorrectly rejected or accepted. Key both counter caches by PoolID (driver and pool) instead of the pool name, matching how the pool map is keyed. PoolID is a comparable value, so the map type now enforces the pool identity: a lookup can no longer be written with the pool name alone. All three allocator variants (stable, incubating, experimental) carry the same shape and are fixed together, and their stale "resource pool names" comments are corrected. Two regression cases live in the shared allocatortesting table so they run against every variant. counter-cache-scoped-by-pool-ID gives the two same-named pools different counter capacities, so it fails unless both caches are keyed by PoolID. counter-cache-not-crossed-between-driver- schemas gives them different counter sets and over-consumes the second, covering the incorrect-accept direction. Both fail on the current code and pass with the change. (cherry picked from commit 2065125)
PrepareResources appends devices to a claim's DriverState as each per-driver NodePrepareResources response comes in. If a driver in the batch returns before the setPrepared step and another driver in the same batch subsequently fails, the successful driver's devices stay in the cache with prepared=false. On retry, isPrepared() is false, so the claim is re-batched, the driver's response is applied again, and its devices end up duplicated in DriverState. This can cause CRI runtimes to fail container start or attach devices twice. Treat the driver's response as authoritative for the (claim, driver) pair: clear the pre-existing device list before rebuilding it from the response.
Store gained Bookmark and LastStoreSyncResourceVersion in kubernetes#134827 without FakeCustomStore being updated, so the fake no longer satisfies cache.Store and downstream test code fails to compile. Add the two func fields and delegating methods following the file's existing pattern, plus a compile-time assertion so a future Store change cannot silently break the fake again.

WalkthroughThis release updates 1.36.3 metadata and dependencies. It also fixes DRA device and counter state, kubelet resize ordering, scheduler gated-pod queue handling, and volume attachment notifications. Tests cover the changed behavior. ChangesRelease 1.36.3 fixes
Priority: ⬇️ Low Estimated code review effort: 4 (Complex) | ~60 minutes Change: Other Merge Risk: 🟠 High · up to One integration test file contains invalid Go and cannot build, so the test suite for scheduler preemption will fail until it is corrected. In the kubelet resize path, failures while initializing recorded container resources are only logged, so a pod sync can report success with incomplete state and later trigger an unnecessary container update or restart. The release changelog still describes 1.36.3 while the image label declares 1.36.4, which should be confirmed before merge. 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

In `@CHANGELOG/CHANGELOG-1.36.md`:
- Line 168: Regenerate the changelog release metadata to consistently target
Kubernetes v1.36.4: update the v1.36.3 release heading and all associated
download URLs in CHANGELOG-1.36.md, matching the version declared by the
hyperkube Dockerfile.
In `@pkg/kubelet/kuberuntime/kuberuntime_manager.go`:
- Around line 2198-2200: Update UpdateActuatedPodLevelResources to preserve
initialization of every container while collecting errors from
setActuatedContainerResources instead of only logging them; after processing all
containers, return an aggregate error so the kubelet caller receives write
failures. Also ensure resize comparison does not treat a missing container
record as zero-valued actuated resources that trigger unnecessary updates or
restarts.
In `@test/integration/scheduler/preemption/preemption_test.go`:
- Line 1074: Replace both invalid new(2) expressions in the preemption test with
pointers to the integer value 2 using the already imported k8s.io/utils/ptr
helper, preserving the *int fields’ expected value and the preemptor’s
createdPods index.

Return container actuated-state write failures.
UpdateActuatedPodLevelResources logs setActuatedContainerResources failures and then continues. The kubelet caller returns an error from this method to abort the current pod sync, but the logged failures never reach that caller.
The resize comparison uses zero-valued actuated resources when a container record is missing. It can therefore schedule an unnecessary UpdateContainerResources call or restart a container. Preserve initialization of all containers, collect the write errors, and return an aggregate after the loop.

Fix the invalid new(2) calls; the package does not compile.
No package-local declaration or dot-import shadows the Go builtin new. Both calls therefore pass the untyped integer constant 2 where new requires a type. The fields are *int, and k8s.io/utils/ptr is already imported.
- count: new(2),
+ count: ptr.To(2),- podRunningPreemption: new(2),
+ podRunningPreemption: ptr.To(2),The preemptor is created after the two victim pods, so its createdPods index is 2.

Replace both invalid new(2) expressions in the preemption test with pointers to
the integer value 2 using the already imported k8s.io/utils/ptr helper,
preserving the *int fields’ expected value and the preemptor’s createdPods
index.
