Subject: Making rcu_normal=1 in RT
Date: Wed, 12 Oct 2016 11:12:51 -0400 [thread overview]
Message-ID: <20161012111251.74d1d52e@redhat.com> (raw)
Hi,
We have the following patch applied to the RT tree:
commit a9d3cc781a3306bfa332fa7cb6134b70696058d5
Author: Josh Cartwright <joshc@ni.com>
Date: Tue Oct 27 07:31:53 2015 -0500
net: Make synchronize_rcu_expedited() conditional on !RT_FULL
However, as noted by Michael, making rcu_normal=1 default in the
RT kernel should have the same effect (ie. not calling
synchronize_sched_expedited()).
So, honest question, is there a reason not to:
1. Drop the patch above
2. Make rcu_normal=1 default?
