Subject: [PATCH v3 0/2] KVM: arm64: nv: Shadow S2 life-cycle fixes
Date: Fri, 21 Aug 2026 17:18:27 +0100 [thread overview]
Message-ID: <20260821161829.1032561-1-maz@kernel.org> (raw)
This is the (hopefully) last revision for this set of fixes for the
shadow S2 life cycle.
* From v2 [1]
- Fixed the nonsensical type used for allocating the nested S2
array, switching to kvmalloc_objs() in the process, guaranteeing
some level of type checking
- Dropped the extra S2 freeing after Wei-Lin pointed out that we are
guaranteed to run the MMU notifier release callback, ensuring that
nothing is left behind
- Collected AB from Lorenzo, with thanks.
