From aa97b9a56906f5965a7c5752790d174cadc8b820 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Thu, 25 Apr 2024 16:18:33 +0200 Subject: rcu/nocb: Fix segcblist state machine stale comments about timers The (de-)offloading process used to take care about the NOCB timer when it depended on the per-rdp NOCB locking. However this isn't the case anymore for a long while. It can now safely be armed and run during the (de-)offloading process, which doesn't care about it anymore. Update the comments accordingly.
