similar to: [PATCH 2/3]: An Implementation of HyperV KVP functionality

Correct issue with not checking kmalloc return value. This fix now only uses one receive buffer for all hv_utils channels, and will do only one kmalloc on init and will return with a -ENOMEM if kmalloc fails on initialize. Thanks to Evgeniy Polyakov <zbr at ioremap.net> for pointing this out. And thanks to Jesper Juhl <jj at chaosbits.net> and Ky Srinivasan <ksrinivasan at

Correct ugly oversight, we need to check the return values of kmalloc and vmbus_recvpacket and return if they fail. I also tightened up the call to kmalloc.

This patch set removes all un-needed DPRINT and printk calls and replaces the remaining ones with the correct pr_, dev_ and netdev_ calls from hv_vmbus, hv_netvsc, hv_timesource and hv_utils. Several DPRINTS are remaining that will be cleaned up in my next set of patches. They deal with printing out certain debugging that will be implemented slightly differently. The remaining hv_storvsc and

Correct issue with not checking kmalloc return value. This fix now only uses one receive buffer for all hv_utils channels, and will do only one kmalloc on init and will return with a -ENOMEM if kmalloc fails on initialize. And properly clean up memory on failure. Thanks to Evgeniy Polyakov <zbr at ioremap.net> for pointing this out. And thanks to Jesper Juhl <jj at chaosbits.net>

From: Hank Janssen <hjanssen at microsoft.com> Addition of new driver for Hyper-V called hv_utils. This driver is intended to support things like KVP, Timesync, Heartbeat etc. This first release has support for graceful shutdown. e.g. Select shutdown from the Hyper-V main admin screen and the Linux VM will do a graceful shutdown.

Address Greg's VmBus audit comments: 1) Leverage driver_data field in struct hv_vmbus_device_id to simplify driver code. 2) Make the util driver conform to the Linux Driver Model. 3) Get rid of the ext field in struct hv_device by using the driver specific data functionality. 4) Other general cleanup. Regards, K. Y
