Revision 70fb3e41a97a5fecc0aedc9a429479d702c3ab66 authored by Ben Gardon on 15 March 2021, 23:38:00 UTC, committed by Paolo Bonzini on 16 March 2021, 18:14:59 UTC
The pt passed into handle_removed_tdp_mmu_page does not need RCU protection, as it is not at any risk of being freed by another thread at that point. However, the implicit cast from tdp_sptep_t to u64 * dropped the __rcu annotation without a proper rcu_derefrence. Fix this by passing the pt as a tdp_ptep_t and then rcu_dereferencing it in the function.
