Petr Mladek 77f81fe08e rcu: Finish folding ->fqs_state into ->gp_state ... Commit commit 4cdfc175c2 ("rcu: Move quiescent-state forcing into kthread") started the process of folding the old ->fqs_state into ->gp_state, but did not complete it. This situation does not cause any malfunction, but can result in extremely confusing trace output. This commit completes this task of eliminating ->fqs_state in favor of ->gp_state. The old ->fqs_state was also used to decide when to collect dyntick-idle snapshots. For this purpose, we add a boolean variable into the kthread, which is set on the first call to rcu_gp_fqs() for a given grace period and clear otherwise.
