Subject: [PATCH tip/core/rcu 14/41] drivers/vhost: Replace synchronize_rcu_bh() with synchronize_rcu()
Date: Sun, 11 Nov 2018 11:43:43 -0800 [thread overview]
Message-ID: <20181111194410.6368-14-paulmck@linux.ibm.com> (raw)
In-Reply-To: <20181111194104.GA4787@linux.ibm.com>
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.
