From: K. Y. Srinivasan Date: Mon, 7 Mar 2011 21:35:48 +0000 (-0800) Subject: Staging: hv: Remove the vm_device structure X-Git-Tag: firefly_0821_release~7613^2~2197^2~218 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=6bad88dac0e648c6978a02c6afb0dc2f4fa484bb;p=firefly-linux-kernel-4.4.55.git Staging: hv: Remove the vm_device structure Consolidate all device related state in struct hv_device by moving the device field from struct vm_device to struct hv_device. As part of this, also get rid of struct vm_device since the consolidation is complete. Signed-off-by: K. Y.
