[Qemu-devel] [PATCH v5 08/12] rdma: introduce qemu_ram_foreach_block()


From: mrhines
Subject: [Qemu-devel] [PATCH v5 08/12] rdma: introduce qemu_ram_foreach_block()
Date: Sun, 21 Apr 2013 17:17:57 -0400

From: "Michael R. Hines" <address@hidden>

This is used during RDMA initialization in order to
transmit a description of all the RAM blocks to the
peer for later dynamic chunk registration purposes.
