Subject: workqueue: Eliminate cond_resched_rcu_qs() in favor of cond_resched()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a7e6425ea5816947d3cb51fbf57351207c074383;p=linux.git

workqueue: 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.
