[PATCH] rcu: Fix incorrect description of default for rcutorture nreaders parameter

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The comment for the nreaders parameter of rcutorture gives the default as
4*ncpus, but the value actually defaults to 2*ncpus; fix the comment.
