From 347e0899b1c75d907f01ac883ca38d37fe9bfa42 Mon Sep 17 00:00:00 2001 From: Andy King Date: Thu, 7 Mar 2013 07:29:08 -0800 Subject: VMCI: Fix process-to-process DRGAMs. When sending between processes, we always schedule a work item. Our work info struct has the message embedded in the middle, which means that we end up overwriting subsequent fields when we copy the (variable-length) message into it. Move it to the end of the struct.
