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.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Stop SyncPod when the pod resize fails.
doPodResizeAction can fail, but Line 1696 only records its SyncResult. SyncPod then generates start configuration and starts containers. A rejected pod cgroup or sandbox resize can therefore start a resized container with the previous pod resource configuration.
Return after adding a failed resize result.

Upgrade golang.org/x/mod to v0.40.0 or later.
The selected v0.37.0 is affected by GO-2026-6179 and GO-2026-6180. Refresh the affected go.mod, go.sum, and vendor entries. The other refreshed golang.org/x modules have no OSV advisories, and golang.org/x/net remains consistently selected at v0.56.0.

Replace both invalid new(2) expressions.
new requires a type argument. The two new(2) expressions prevent compilation. Use ptr.To(2) for both fields.
