RE: [PATCH v5 06/13] iommu: Add iommu_copy_struct_from_full_user_array helper

The iommu_copy_struct_from_user_array helper can be used to copy a single entry from a user array which might not be efficient if the array is big.

Add a new iommu_copy_struct_from_full_user_array to copy the entire user array at once. Update the existing iommu_copy_struct_from_user_array kdoc accordingly.

what about:

iommu_copy_struct_from_user_array_single() iommu_copy_struct_from_user_array_full()

?
