• Use atomic Add(1) when updating completed_spans_ in CentralFreeList::DeallocateSpans, which executes without CentralFreeList::lock_ held.

• Increment resize_[cpu].capacity before resize_[cpu].available in CpuCache::StealFromOtherCache to preserve the available <= capacity invariant across lockless updates (latent/masked bug).

• Use relational bounds (capacity < max_capacity and capacity >= max_capacity) in CpuCache::UpdateCapacity to avoid unsigned size_t underflow when capacity > max_capacity (latent/masked bug).

• Avoid transient negative counter_ (and size_t wraparound in length()) during CentralFreeList::InsertRange by adding batch.size() before subtracting deallocated spans (latent/masked telemetry bug).

• Clamp to_return to low_water_mark_ and preserve lower low_water_mark_ across lock drops in TransferCache::TryPlunder.

• Prevent HugePageUnbackedTrackerTreatment::Restore from overwriting unbroken and maybe_hugepage_backed on a PageTracker that was concurrently subreleased while pageheap_lock was dropped.

• Fix backed-memory accounting leak when unback_without_lock_ fails on a partially subreleased PageTracker in HugePageFiller::HandleFullyFreedTracker.

• Shrunk TrackerFeatures from 40 bytes -> 16 bytes by compressing integers and bits.

• Shrink ThreadCache FreeList size by downsizing its members (lowater_, max_length_, length_overages_) to uint16_t, and its base class LinkedList::length_ to uint16_t.

• Optimize TransferCache footprint by downsizing miss counters and combining them into the first cache line.

  #1095·copybara-service[bot] opened Sep 24, 2026Bot·

• This change downsizes PerClassMissCounts and MissCounts to use std::atomic<uint32_t> instead of size_t. Size class miss counters don't overflow their 32-bit width fast enough to pose a problem within evaluation intervals, so uint32_t suffices.
