Commit-ID: d05faa5f1ac50beef77b4ceba0e8e157d41146e2 Gitweb: https://git.kernel.org/tip/d05faa5f1ac50beef77b4ceba0e8e157d41146e2 Author: Paul E.

McKenney <paulmck at linux.ibm.com> CommitDate: Tue, 27 Nov 2018 09:21:37 -0800 drivers/vhost: Replace synchronize_rcu_bh() with synchronize_rcu() Now that synchronize_rcu() waits for bh-disable regions of code as well as RCU read-side critical sections, synchronize_rcu_bh() can be replaced by synchronize_rcu(). This commit therefore makes this change. Signed-off-by: Paul E. McKenney <paulmck at linux.ibm.com> Cc: "Michael S.
