Subject: [PATCH tip/core/rcu 2/6] srcu: Change printk() %p to %pK
Date: Fri, 1 Dec 2017 11:41:56 -0800 [thread overview]
Message-ID: <1512157320-23205-2-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20171201194139.GA22722@linux.vnet.ibm.com>
This commit changes the %p printk() in rcutorture to %pK. This could
be considered irrelevant, given that any user able to start rcutorture
could inflict far heavier damage on the system, but it doesn't hurt to
change it and doing so avoids script-generated noise.
