Subject: [PATCH tip/core/rcu 8/8] rcu: Add advice to PROVE_RCU_REPEATEDLY kernel config parameter
Date: Wed, 22 Sep 2010 17:50:53 -0700 [thread overview]
Message-ID: <1285203053-22068-8-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20100923005033.GA22006@linux.vnet.ibm.com>
The PROVE_RCU_REPEATEDLY has no "Say Y"/"Say N" advice, so this commit
adds it.
