Some work in progress on the ucoredump bits (D51377) would pass the compression format out-of-band to the coredump writer's init function, but the compressor is accessible to the init_fn via the coredump_params. Making this accessible in parts of the kernel detached from the bits actually doing compression would be useful to clean up the API so that we can stick to using coredump_params to pass along whatever may be useful.
