> Cassandra’s {{NativeLibrary.trySkipCache}} incorrectly moves the file offset
> backward when splitting page-cache eviction ranges larger than ~2 GiB.
> Subsequent {{posix_fadvise}} calls may use negative offsets and fail, leaving
> part of the file cached.
> Fix {{offset -= sublen}} to {{offset += sublen}} and add boundary and
> multi-chunk unit tests.
