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.

The default timeout routine used for FC transport is not

managed by storvsc driver do not have an rport associated

The first two patches in this series are a resend; these were submitted
some months ago and as far as I know, there were no outstanding issues.
Win8 and win8 r2 hosts do support SPC-3 features but claim SPC-2 compliance.
This issue is fixed here as well.

Drivers: scsi
claiming SPC-3 compliance on these hosts as well. This will enable TRIM
support on these hosts.

Get rid of the warning messages since they will clutter up various system logs
and are of questionable value to the end user. For debugging purposes, this
information can be gotten by setting the scsi log level appropriately.

The virtual HBA that storvsc implements can support multiple channels and
targets. So, scan the host when the host notifies that a scan is needed.

This patch-set addresses issues with LUN hot-add and remove. When the host
notifies the guest that a scan is needed, scan the host. Also, prior to
discovering new devices that may have been added, ensure we handle the
LUN remove case first.

Drivers: scsi: storvsc: In
for an I/O to remove the device, force the discovery of
LUNs that may have been removed prior to discovering LUNs that may have
been added.

Add blist flags to permit the reading of the VPD pages even when
the target may claim SPC-2 compliance. MSFT targets currently
claim SPC-2 compliance while they implement post SPC-2 features.
With this patch we can correctly handle WRITE_SAME_16 issues.

On Azure, we have seen instances of unbounded I/O latencies. To deal with
this issue, implement handler that can reset the timeout. Note that the
host gaurantees that it will respond to each command that has been issued.
