49619dfd77 scst: Fix scst_suspend_activity() timeout handling 
Make sure that suspend_count is decremented if scst_suspend_activity()
times out. Also, if a timeout is encountered, clear SCST_FLAG_SUSPENDING
before waking up the command threads instead of after waking up these
threads.

84f6cb5dae scst_vdisk: Add support for nullio "dummy" LUNs 
While the SCSI specifications require presence of LUN 0 it is not always
desirable to associate storage with LUN 0. Hence allow LUN 0 (or any
other LUN) to be configured such that it does not appear at the
initiator side. This is realized by adding a "dummy" attribute in to
NULLIO vdisk devices. If that attribute is set, the PERIPHERAL QUALIFIER
field in the INQUIRY response is set to 1 and the PERIPHERAL DEVICE TYPE
is set to 0x1f. Add an example in the scst.conf(5) man page that shows
how to use the new attribute.

2093dd7561 Make it possible to forcibly close SRP and FC sessions via sysfs 
That patch contains the following changes:
* Move the code for creating a "close_sess" sysfs attribute from iscsi-scst to
  the SCST core such that it becomes available for other target drivers. This
  does not change the functionality of iscsi-scst.
* Add code in ib_srpt and qla2x00t to allow a session to be forcibly closed from
  user space.
