Could we please have a full, standalone changelog for this patch? The 620951e27457 changelog says "Without this, the kernel crashes...". Does your patch also fix a crash? If so under what circumstances and should we backport this fix into -stable kernels? Etcetera. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
