From 92760499d01ef91518119908eb9b8798b6c9bd3f Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Fri, 30 May 2008 16:05:53 +0200 Subject: KVM: kvm_io_device: extend in_range() to manage len and write attribute Modify member in_range() of structure kvm_io_device to pass length and the type of the I/O (write or read). This modification allows to use kvm_io_device with coalesced MMIO.
