This struct member was used to track whether a domain change requires updates to the device-table and IOMMU cache flushes. The problem is, that access to this field is racy since locking in the common mapping code-paths has been eliminated. Move the updated field to the stack to get rid of all potential races and remove the field from the struct. Fixes: 92d420e ("iommu/amd: Relax locking in dma_ops path") Reviewed-by: Filippo Sironi <[email protected]> Reviewed-by: Jerry Snitselaar <[email protected]> Signed-off-by: Joerg Roedel <[email protected]>
