[PATCH v3 0/7] mm/kvm: Improve parallelism for access bit harvesting

2024-04-01 Thread James Houghton
This patchset adds a fast path in KVM to test and clear access bits on sptes without taking the mmu_lock. It also adds support for using a bitmap to (1) test the access bits for many sptes in a single call to mmu_notifier_test_young, and to (2) clear the access bits for many ptes in a single call
