When KERNEL_LZ4 is set, we always get an output even when building with 'make -s': *** LZ4 Compression CLI , by Yann Collet (May 31 2013) *** ! Generating compressed LZ4 using Legacy format (deprecated !) ! Using stdin for input Using stdout for output Compressed 11213376 bytes into 4555781 bytes ==> 40.63% Done in 0.63 s ==> 16.97 MB/s The output is not helpful in the context of building the kernel, so this patch hides the stdout output of the lz4 binary completely. We could also try to not hide the output when building without '-s', but I could not come up with any use for that.
