Drivers: hv: utils: fix hvt_op_poll() return value on transport
destroy
drivers/hv/channel_mgmt.c |3
From: Vitaly Kuznetsov
The return type of hvt_op_poll() is unsigned int and -EBADF is
inappropriate, poll functions return POLL* statuses.

For performance critical devices, we distribute the incoming
channel interrupt load across available CPUs in the guest.
Include Fibre channel devices in the set of devices for which
we would distribute the interrupt load.

Add vendor and device attributes to VMBUS devices. These will be used
by Hyper-V tools as well user-level RDMA libraries that will use the
vendor/device tuple to discover the RDMA device.

Cleanup vmbus_set_event() by inlining the hypercall to post
the event and since the return value of vmbus_set_event() is not checked,
make it void. As part of this cleanup, get rid of the function
hv_signal_event() as it is only callled from vmbus_set_event().

For FC devices managed by this driver, atttach the appropriate transport
template. This will allow us to create the appropriate sysfs files for
these devices. With this we can publish the wwn for both the port and the node.

The function storvsc_channel_init() repeatedly interacts with the host to
extract various channel properties. Refactor this code to eliminate code
repetition.

Some miscellaneous fixes.

scsi: storvsc: Install the storvsc specific timeout handler for FC
devices
scsi: storvsc: Use the specified target ID in device lookup
drivers/scsi/storvsc_drv.c | 12 ++--

The default timeout routine used for FC transport is not
suitable for FC devices managed by storvsc since FC devices
managed by storvsc driver do not have an rport associated
with them. Use the time out handler used for SCSI devices
for FC devices as well.

The current code assumes that there is only one target in device lookup.
Fix this bug. This will alow us to correctly handle hot reomoval of LUNs.

The default user scan function associated with FC (fc_user_scan)
is not suitable for FC hosts on Hyper-V since we don't have
an rport associated with FC host on Hyper-V . Set it to NULL so we can
support manual scan of FC targets on Hyper-V.
