[PATCH 0/2] KVM: arm64: Mark a couple of variables static
by Quentin Perret
The kernel test bot is complaining (and rightfully so) about variables
introduced by the host stage-2 series that should be static. This series
fixes all of them.
Thanks!
Quentin Perret (2):
KVM: arm64: Mark pkvm_pgtable_mm_ops static
KVM: arm64: Mark the host stage-2 memory pools static
