[PATCH 0/2] KVM: arm/arm64: vgic-its: Guest memory access fixes

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

 



While messing with something completely different, I managed to
trigger a number of RCU warnings, due to the lack of srcu locking
in the ITS code.

Andre partially addressed those last year[1], but there was some
more left.
