    lib: zstd: Add kernel-specific API · cf30f6a5
    Nick Terrell authored
    This patch:
    - Moves `include/linux/zstd.h` -> `include/linux/zstd_lib.h`
    - Updates modified zstd headers to yearless copyright
    - Adds a new API in `include/linux/zstd.h` that is functionally
      equivalent to the in-use subset of the current API. Functions are
      renamed to avoid symbol collisions with zstd, to make it clear it is
      not the upstream zstd API, and to follow the kernel style guide.
    - Updates all callers to use the new API.
    
    There are no functional changes in this patch. Since there are no
    functional change, I felt it was okay to update all the callers in a
    single patch. Once the API is approved, the callers are mechanically
    changed.
    
    This patch is preparing for the 3rd patch in this series, which updates
    zstd to version 1.4.10. Since the upstream zstd API is no longer exposed
    to callers, the update can happen transparently.
