From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> 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, Signed-off-by: Nicholas A.
