[PATCH 0/4] target: Eliminate se_port + t10_alua_tg_pt_gp_member

["Nicholas A. Bellinger" <nab@daterainc.com>]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi folks,

Here is a -v1 series with HCH's recent changes to go ahead and drop
all se_port + t10_alua_tg_pt_gp_member usage within target-core in
favor of direct se_lun pointer dereference.

This includes the original patch + minor fixes, along with two other
improvements for killing off se_lun->lun_sep_lock via RCU pointer
access, and converting the remaining se_lun->lun_active busy-wait
special cases to existing percpu se_lun->lun_ref access.

Also included in the series is a recently discussed change to go
ahead and drop an unnecessary core_tpg_register() parameter, and
all associated target_core_fabric_ops forward declartions within
fabric driver code.

Please review.
