Hi, I applied this patch and ran it on my UP2000+ The kernel builds and boots, and I verified the new lib/raid/xor/alpha implementation using the XOR KUnit test, the test passed, see below: [ 25.705064] KTAP version 1 [ 25.705064] # Subtest: xor [ 25.705064] # module: xor_kunit [ 25.705064] 1..1 [ 28.957992] # xor_test: Test should be marked slow (runtime: 3.253413330s) [ 28.958969] ok 1 xor_test Acked-by: Magnus Lindholm <[email protected]> Tested-by: Magnus Lindholm <[email protected]>
