4c269fa728 In the current implementation of SCST/trunk the recently introduced 
"active" attribute for vdisk_blockio devices is managed by an ALUA
state change (start/finish), for specific ALUA states (eg,
active/standby). Relying on ALUA state changes to open/close the
back-end block device does indeed work for some SCST configurations,
however, some users desire advanced control over this setting, and
prefer to handle opening/closing a back-end block device from the
cluster resource agent (RA) script. Certain ambiguous situations can
also arise if more than one target group exists per SCST device
group... in this case, a back-end device may flip/flop (opened/closed)
and may end up in an inconsistent state if care is not taken in the
implementation of the cluster RA.

The patch below makes the "active" sysfs attribute for vdisk_blockio
readable/writable by a user, thereby giving full control over a
device's opened/closed state. The default behavior for SCST
vdisk_blockio devices is to allow ALUA state changes to control the
opened/closed ("active") state of a back-end device
(bind_alua_state=1). If the user wishes to handle setting the "active"
attribute themselves via a script or cluster RA, they would set
bind_alua_state=0 for the vdisk_blockio device, and the "active"
attribute would not be modified on ALUA state changes, it is then left
up to the user to handle this.

The patch below also fixes a bug where the attribute value is not
changed when the appropriate ALUA state is set, unless a target
session exists for the target group target; see here for more
information: https://sourceforge.net/p/scst/mailman/message/35898014/

283b30f603 scst: add thread_index sysfs attribute 
This attribute exports per LUN thread index assigned by
scst_add_threads(). It can be used to look up which export thread is
serving which target since this index also appears in the export thread
name. This information then could be used to set CPU affinity for those threads to improve performance.
