Making rcu_normal=1 in RT

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

We have the following patch applied to the RT tree:

  commit a9d3cc781a3306bfa332fa7cb6134b70696058d5
  Author: Josh Cartwright <joshc@xxxxxx>
  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?
