This is an old commit that failed to handle any torture_type other than
"rcu", including the "srcu" that you tested with. It has since been
replaced by a series of newer commits fixing this and other bugs, with
the current version here:
c815d319a933 ("rcutorture: Make rcutorture_one_extend() check reader state")
Does this one work for you?
Either way, thank you for your testing efforts!
Thanx, Paul
