[PATCH v12 66/84] KVM: LoongArch: Mark "struct page" pfn accessed before dropping mmu_lock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Mark pages accessed before dropping mmu_lock when faulting in guest memory
so that LoongArch can convert to kvm_release_faultin_page() without
tripping its lockdep assertion on mmu_lock being held.
