size_t

src_size

This is a kernel-style API that wraps the upstream zstd API, which cannot be used directly because the symbols aren't exported. It exposes the minimal functionality which is currently required by users of zstd in the kernel. Expose extra functions from lib/zstd/zstd.h as needed. zstd_compress_bound() - maximum compressed size in worst case scenario @src_size: The size of the data to compress.

Return: The maximum compressed size in the worst case scenario.
