similar to: [patch 00/54] [Announce] Microsoft Hyper-V drivers for Linux

From: Hank Janssen <hjanssen at microsoft.com> Removed TODO for VMBUS, it mirrors HYPER-V behaviour to closely and does not really share any usable functionality of the Linux kernel facilities. There is not really an easy way to combine functionality. Signed-off-by:Hank Janssen <hjanssen at microsoft.com> Signed-off-by:Haiyang Zhang <haiyangz at microsoft.com> ---

From: Hank Janssen <hjanssen at microsoft.com> Increased storvsc ringbuffer and max_io_requests. This now more closely mimics the numbers on Hyper-V. And will allow more IO requests to take place for the SCSI driver.

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.

More cleanup. In this patch-set we deal with the following issues: 1) While a Linux guest on Hyper-V can be assigned removable media devices (DVD, floppy etc), these devices are not handled by the Hyper-V block driver. So, we cleanup all the dead code dealing with removable media devices. 2) There were multiple functions to retrieve information about the device. Since much of

The latest upstream merge changed struct block_device_operations: This merge got rid of blkvsc_media_changed and introduced the function blkvsc_check_events. This broke all the patches that were sent after the tree was closed the last time. This is a resend of this patch-set to account for this change in the kernel. More cleanup.

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

Further cleanup of the hv drivers: 1) Cleanup the reference counting mess for both stor and net devices. 2) Handle all block devices using the storvsc driver. 3) Accomodate some host side scsi emulation bugs. 4) In case of scsi errors off-line the device. Regads, K. Y

From: Hank Janssen <hjanssen at microsoft.com> If we get a SCSI host bus reset we now gracefully handle it, and we take the device offline. This before sometimes caused hangs.
