[PATCH Target_Core_Mod 0/12]: Make v3.0 storage engine code generic

["Nicholas A. Bellinger" <nab@linux-iscsi.org>]

Greetings all,

This patch series adds generic se_portal_group_t and se_node_acl_t
functionality.  It also removes virtually all LIO-Target and iSCSI
target code from Target_Core_Mod/ConfigFS.  They are made against
against lio-core-2.6.git/master and tested on
v2.6.28-rc7.

To see the bleeding edge of generic target development using multiple
Linux storage subsystems using ConfigFS, please have a look at:

Here are the patches:

[Target_Core_Mod 1/12] Add generic target portal group infrastructure
[Target_Core_Mod 2/12]: Add generic target se_device_t and LUN ACL infrastructure
[Target_Core_Mod 3/12]: Update struct target_core_fabric_ops API
[Target_Core_Mod 4/12]: Updates for target_core_base.h
[Target_Core_Mod 5/12]: Remove iSCSI includes from target_core_seobj.c
[Target_Core_Mod 6/12]: Updates for target_core_hba.c
[Target_Core_Mod 7/12]: Update generic REPORT_LUN code
[Target_Core_Mod 8/12]: Update SE Object code for target_core_base.h
[Target_Core_Mod 9/12]: Update PSCSI, IBLOCK, FILEIO and RAMDISK subsystem plugins
[Target_Core_Mod/MIB 10/12]: Update SCSI MIBs
[Target_Core_Mod 11/12]: Update target_core_transport.c for new generic code
[Target_Core_Mod/ConfigFS 12/12]: Remove do_configfs_mkdir() and do_configfs_rmdir()
