From 6083abd9aa134c9b0804e584f8279f54e6c90a1c Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Tue, 31 Jan 2012 19:44:41 +0100 Subject: linux-user: add struct old_dev_t compat The compat LOOP_SET_STATUS ioctl uses struct old_dev_t in its passed struct. That variable type is vastly different between different architectures. Implement wrapping around it so we can use it. This fixes running arm kpartx on an x86_64 host for me.
