From 77dc174103fdb121c47621e9856d73704b7eddd2 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 15 Sep 2020 15:41:50 -0700 Subject: rcu-tasks: Convert rcu_tasks_wait_gp() for-loop to while-loop The infinite for-loop in rcu_tasks_wait_gp() has its only exit at the top of the loop, so this commit does the straightforward conversion to a while-loop, thus saving a few lines.
