Subject: [PATCH 07/11] liblockdep: prevent multiple declarations of CALLER_ADDR0
Date: Wed,  6 Feb 2013 17:11:30 -0500	[thread overview]
Message-ID: <1360188694-25077-8-git-send-email-sasha.levin@oracle.com> (raw)
In-Reply-To: <1360188694-25077-1-git-send-email-sasha.levin@oracle.com>

They are declared once in the public and once in the private headers, prevent
declaring them twice if both headers are used.
