Thanks for the feedback. Do you mean the CC stable kernel tag? Something like: "Cc: [email protected] # v5.8+"? > Can you please add a Fixes tag? Fixes: 0bbeb01a4faf ("iommu/vt-d: Manage scalalble mode PASID tables") Do you want me to send a v2 with the CC stable kernel tag and Fixes tag? Or, do you just need to take the Fixes tag directly without sending a v2? -- Adrian _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
