From 2f20de99a63b0de9bcceedafc3281e65fbf7d4fd Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Sun, 11 Apr 2021 10:49:52 -0700 Subject: rcu: Make rcu_gp_cleanup() be noinline for tracing Although there are trace events for RCU grace periods, these are only enabled in CONFIG_RCU_TRACE=y kernels. This commit therefore marks rcu_gp_cleanup() noinline in order to provide a function that can be traced that is invoked near the end of each grace period. Signed-off-by: Paul E.
