Dear Linux community, I am leading a project at Samsung where we utilized your kernel 5.15 in our system. Recently we faced an important kernel panic issue whose fix must be following patch: https://lore.kernel.org/all/1946ef9f774851732eed78760a78ec40dbc6d178.1667591503.git.robin.murphy@xxxxxxx/ The problem for us is that this patch must be available from kernel 6.1 onwards. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/iommu/iommu.c?h=v6.1.119 Clear to us is that it is not integrated into K5.15 yet: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/iommu/iommu.c?h=v5.15.173 On the other side we can see that this patch was already applied to Android Common Kernel android13-5.15 https://android-review.googlesource.com/q/I51dbcdc5dc536b0e69c6187b2d7ac6a2031a305b. In particular, we can see the same implementation in the recent ACK release https://android.googlesource.com/kernel/common/+/refs/tags/android13-5.15-2024-11_r2/drivers/iommu/iommu.c given on https://source.android.com/docs/core/architecture/kernel/gki-android13-5_15-release-builds Do you have any plan to adjust your implementation in drivers/iommu/iommu.c in K5.15 as present in K6.1? If not, since the issue in our project is very critical for us, may I ask you kindly to trigger the sync of K5.15 and K6.1 soon? I would appreciate highly your response and any support.
