[PATCH 0/4] target: Move backend memory release to configfs_item_operations->release()

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

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

Greetings all,

This series addresses four scenarios in backend HBA/DEV target_core_configfs.c
code where config_item_put() being called upon the following TCM config_groups:

	struct se_hba->hba_group

	struct se_subsystem_dev->se_dev_group

	struct t10_alua_lu_gp->lu_gp_group

	struct t10_alua_tg_pt_gp->tg_pt_gp_group

and subsequently releasing memory of these four parent TCM data structures
is causing a number of SLUB 'Poison overwritten' warnings during slub_debug=FPUZ
testing with .38-rc2 code.

This series addresses the issue by using moving existing release logic
of the parent structure containing a struct_config_group into it's own
seperate struct configfs_item_operations->release() callback.

Please review and comment,
