I noticed after this commit LZ4 decompression is slower. ulz4fn function call takes 1.209670 seconds with this commit. After reverting this commit, the ulz4fn function call takes 0.587032 seconds. I am decompressing a LZ4 compressed kernel (compressed with lz4 v1.9.4 using -9 option for maximum compression) on RK3399. Any ideas why it is slower with this commit and how the performance regression can be fixed? Thanks. Regards, Jonathan
