Subject: [PATCH] rpmsg: virtio_rpmsg_bus: replace "%p" with "%pK"
Date: Tue, 23 Oct 2018 20:19:09 -0500 [thread overview]
Message-ID: <20181024011909.21674-1-s-anna@ti.com> (raw)
The virtio_rpmsg_bus driver uses the "%p" format-specifier for
printing the vring buffer address. This prints only a hashed
pointer even for previliged users. Use "%pK" instead so that
the address can be printed during debug using kptr_restrict
sysctl.
