And I believe that I found my bug in this commit (lots more testing still
required, but the preponderance of evidence and all that):
2cc0c7f07143 ("rcu: Eliminate ->rcu_qs_ctr from the rcu_dynticks structure")
So it really isn't your fault.
Of course, the real reason for the lack of fault on your part will not
because I believe I found the bug elsewhere, but instead because I will
be dropping your patch (and mine as well) on Frederic's advice. ;-)
Thanx, Paul
