From 1eac0075ebeecbf5c972f575ac448a0ea92e4f3a Mon Sep 17 00:00:00 2001 From: Juri Lelli Date: Tue, 10 Aug 2021 10:48:16 +0200 Subject: [PATCH] rcu: Make rcu update module parameters world-readable rcu update module parameters currently don't appear in sysfs and this is a serviceability issue as it might be needed to access their default values at runtime. Fix this issue by changing rcu update module parameters permissions to world-readable. Suggested-by: Paul E. McKenney Signed-off-by: Juri Lelli Signed-off-by: Paul E.
