Sebastian Andrzej Siewior ced38c8c00 target: tcm_mod_builder: small fixups
This includes:
- remove on _ in "__NAMELEN" in $fabric _make_tport
- target_fabric_configfs_init() returns an error pointer and not NULL
  anymore. Consider that.
- replace (!(var_name)) with (!var_name). The extra () are not required
- remove #ifdef MODULE. If the code is builtin it needs an init function
  or the code is useless
- put exit/clean functions into __exit

Nicholas Bellinger 77271de645 Documentation/target: Fix tcm_mod_builder.py build breakage
This patch fixes TFO->release_cmd() and removes legacy pack_lun() usage
and new_cmd_failure when generating new TCM fabric skeleton from the
tcm_mod_builder.py script.

Christoph Hellwig c4795fb20e target: header reshuffle, part2
This reorganized the headers under include/target into:

 - target_core_base.h stays as is with all target-wide data stuctures and defines
 - target_core_backend.h contains the whole interface to I/O backends
 - target_core_fabric.h contains the whole interface to fabric modules

Except for those only the various configfs macro headers stay around.

Fubo Chen f45934e08c [SCSI] tcm_mod_builder.py: Fix generated *_drop_nodeacl() handler
This patch adds the missing core_tpg_del_initiator_node_acl() call required
by fabric modules for struct se_node_acl->acl_group context shutdown via

	target_core_fabric_configfs.c:target_fabric_nacl_base_release() ->

		struct target_core_fabric_ops->fabric_drop_nodeacl()

for tcm_mod_builder.py generated $FABRIC_MOD_configfs.c skeleton code.

Nicholas Bellinger 10635c8b71 [SCSI] target: tcm_mod_builder.py generated Makefile cleanups
This patch converts the tcm_mod_builder.py generation script to
create a new drivers/target/$TCM_FABRIC_MOD/Makefile and update
drivers/target/Makefile, instead of creating+updating a 'Kbuild'
filename.

It also removes the remaining EXTRA_CFLAGS includes from
tcm_mod_build_kbuild(), and converts fabric module generated .c
code to us ""-style includes for $FABRIC_MOD_[base,fabric].h

Nicholas Bellinger c66ac9db8d [SCSI] target: Add LIO target core v4.0.0-rc6
LIO target is a full featured in-kernel target framework with the
following feature set:

High-performance, non-blocking, multithreaded architecture with SIMD
support.

Advanced SCSI feature set:

    * Persistent Reservations (PRs)
    * Asymmetric Logical Unit Assignment (ALUA)
    * Protocol and intra-nexus multiplexing, load-balancing and failover (MC/S)
    * Full Error Recovery (ERL=0,1,2)
    * Active/active task migration and session continuation (ERL=2)
    * Thin LUN provisioning (UNMAP and WRITE_SAMExx)

Multiprotocol target plugins

Storage media independence:

    * Virtualization of all storage media; transparent mapping of IO to LUNs
    * No hard limits on number of LUNs per Target; maximum LUN size ~750 TB
    * Backstores: SATA, SAS, SCSI, BluRay, DVD, FLASH, USB, ramdisk, etc.

Standards compliance:

    * Full compliance with IETF (RFC 3720)
    * Full implementation of SPC-4 PRs and ALUA

Significant code cleanups done by Christoph Hellwig.

[jejb: fix up for new block bdev exclusive interface. Minor fixes from
 Randy Dunlap and Dan Carpenter.]
