We need to update the description of the patch to clarify that it applies to other GPU programming models as well. When the patch was uploaded SYCL targeted OpenCL kernels only and today the downstream implementation can target CUDA, HIP and Intel oneAPI Level Zero kernels as well.
SYCL kernel is defined as C++ callable type, but typical GPU kernel interface is a C-like function. In addition to that there might be additional restrictions on passing data from the host system (e.g. image types can be passed as a member of C++ class, etc.). The solution here is emit a wrapper function, which initializes and invokes SYCL callable object.

Does it answer your question or you would like to see changes in addition to the description update?
