From e8755d2bde7c296026fe5d47f1b75c7b19ba46fd Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 4 Aug 2022 17:34:30 -0700 Subject: rcu: Remove expedited grace-period fast-path forward-progress helper Now that the expedited grace-period fast path can only happen during the pre-scheduler portion of early boot, this fast path can no longer block run-time RCU Trace grace periods. This commit therefore removes the conditional cond_resched() invocation. Signed-off-by: Paul E.
