question about arch/riscv/kvm/mmu.c

[Julia Lawall <julia.lawall@xxxxxxxx>]

Hello,

The function kvm_riscv_stage2_map contains the code:

mmu_seq = kvm->mmu_notifier_seq;

I noticed that in every other place in the kernel where the
mmu_notifier_seq field is read, there is a read barrier after it.  Is
there some reason why it is not necessary here?

thanks,
julia
