A function to send the type of message is also added.
The coming net/hvsock driver will use this function to proactively request
the host to offer a VMBus channel for a new hvsock connection.

Some miscellaneous fixes.
V2: addressed comments from Hannes Reinecke
K. Y. Srinivasan (2):
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 | 16 +++-
1
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.

V2: Made lun and target_id unsigned 8 bit entities - Hannes
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.

clocksource_change_rating() involves mutex usage and can't be called
in interrupt context. It also makes sense to avoid doing redundant work
on crash.

When the hvsock channel's outbound ringbuffer is full (i.e.,
hv_ringbuffer_write() returns -EAGAIN), we should avoid the unnecessary
signaling the host.

we don't initialize some
cpus in Linux, e.g. when we boot with 'nr_cpus=' limitation.
Avoid the infinite loop in init_vp_index() by checking that we still have
non-used CPUs in the alloced_cpus_in_node mask and resetting it in case
we don't.
