From c90e3ecc91584558d24c82940a3651fdfc174be0 Mon Sep 17 00:00:00 2001 From: Onkarnath Date: Thu, 11 Jan 2024 14:57:22 +0530 Subject: rcu/sync: remove un-used rcu_sync_enter_start function With commit '6a010a49b63a ("cgroup: Make !percpu threadgroup_rwsem operations optional")' usage of rcu_sync_enter_start is removed. So this function can also be removed. In the words of Oleg Nesterov: __rcu_sync_enter(wait => false) is a better alternative if someone needs rcu_sync_enter_start() again.
