Subject: [PATCH 1/3] s390: Expose a constant for the number of words representing the CRs
Date: Tue, 3 Mar 2009 10:56:02 -0500 [thread overview]
Message-ID: <1236095764-19325-2-git-send-email-danms@us.ibm.com> (raw)
In-Reply-To: <1236095764-19325-1-git-send-email-danms@us.ibm.com>
We need to use this value in the checkpoint/restart code and would like to
have a constant instead of a magic '3'.
