Subject: [PATCH] librdmacm: fix compiler warning of void* arithmetic
Date: Fri, 22 Oct 2010 11:00:22 +0100	[thread overview]
Message-ID: <i9rnbn$f9o$1@dough.gmane.org> (raw)

Arithmetic on void* pointers generates a compiler warning, and projects
that include rdma/rdma_verbs.h and compile with  -Werror -Wall will fail
to build.
