Subject: [PATCH 0/2] [Target_Core_Mod/Persistent_Reservations]: Add implict
	release and PROUT CLEAR SA

Greetings all,

This first patch series adds implict release of PR reservations/registrations when
a $FABRIC_MOD logical unit ACL is being released through target_core_mod/ConfigFS.
The second patch adds support for the PROUT CLEAR service action that allows a registered
I_T nexus (eg: initiator port) to release PR reservations/registrations.  This is one of
the PROUT service actions that various client side cluster code / SCSI subsystem initiators
use with SCSI persistent reservations for fencing of failed nodes.

These patches are made against lio-core-2.6.git/master and tested on
v2.6.29-rc8 x86 32-bit HVM using sg_persist from sg3_utils.  The lio-core-2.6.git tree
can be found at:
