Hi,
We can not get the EBUSY from " echo 0 > /sys/devices/system/memory/memoryxxx/online", maybe, redirect the error ouput to /dev/null is suitable when calling offline_memory_expect_success():

Can we have here an output like
online->offline memory0
-> Failure
online->offline memory10
-> Success
That would make much more sense for debugging purposes and understanding
what is happening here. I was primarily concerned about the misleading
error message, that indicated that something is "unexpected" -- it's
perfectly reasonable here to *expect* that offlining a random memory
blocks just fails.
