[Qemu-devel] [PATCH v3 01/17] scripts/update-linux-headers.sh: pull virt


From: Michael S. Tsirkin
Subject: [Qemu-devel] [PATCH v3 01/17] scripts/update-linux-headers.sh: pull virtio hdrs
Date: Mon, 16 Feb 2015 22:35:25 +0100

It doesn't make sense to copy values manually:
the only issue with getting headers from linux
seems to be dealing with linux/types, we
can easily fix that automatically while importing.
