Greetings,

0day kernel testing robot got the below dmesg and the first bad commit is

Umm.  I don't see a 'suspicious RCU usage' message in here.  I see a
lot of vmalloc warnings ... ?

Never mind, the RCU warnings were in one of the attached dmesg files.
I found the problem; it's in the test-suite and not something that could
lead to any real problems today.

Thanks for the report!
