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()
I am okay with that, yet might prefer that in a separate patch? As I am trying to reduce the number of changes in the series since we are likely merging three series at once :)
Thanks Nicolin
