Submitter sent bug report, it seems no kernel developer ever bothered
to answer.

The unresponsive side is not the submitter.

Linus just restarted discussing this one and #10629.

My impression of both bugs is that not that Alexey was unresponsive but 
that noone else was able to reproduce it.

  erk.  It'll make me a week to bisect this.  I suppose I can plod away
  at it in the background, but I won't be able to do that until the end
  of this month.


And "repeatable slab corruption" is not exactly a good regression
to ignore...
