Subject: mm: Eliminate cond_resched_rcu_qs() in favor of cond_resched()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=50d4fb781287b47c4c2d455e3395783c1f06a3a5;p=linux.git

mm: Eliminate cond_resched_rcu_qs() in favor of cond_resched()

Now that cond_resched() also provides RCU quiescent states when
needed, it can be used in place of cond_resched_rcu_qs().  This
commit therefore makes this change.
