[PATCH OLK-6.6] ftrace: Use asynchronous grace period for register_ftrace_direct()

From: "Paul E. McKenney" <paulmck(a)kernel.org> mainline inclusion from mainline-v6.10-rc1 commit 33f137143e651321f10eb67ae6404a13bfbf69f8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICRTKA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When running heavy test workloads with KASAN enabled, RCU Tasks grace periods can extend for many tens of seconds, significantly slowing trace registration. Therefore, make the registration-side RCU Tasks grace period be asynchronous via call_rcu_tasks().
