From 2b0ce0797d6bfb13ebefe010da86abced0b7a9b3 Mon Sep 17 00:00:00 2001 From: "Michael R. Hines" Date: Tue, 25 Jun 2013 21:35:28 -0400 Subject: rdma: introduce qemu_update_position() RDMA writes happen asynchronously, and thus the performance accounting also needs to be able to occur asynchronously. This allows anybody to call into savevm.c to update both f->pos as well as into arch_init.c to update the acct_info structure with up-to-date values when the RDMA transfer actually completes.
