target: reshuffle headers Create a new headers, drivers/target/target_core_internal.h that is supposed to hold all target_core-internal prototypes. Move all non-exported includes from include/target to it, and merge the smaller prototype-only includes inside drivers/target into it as well. Mark functions that were found to not be called outside their implementation file static. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>

target: Fix lookup of dynamic NodeACLs during cached demo-mode operation This patch fixes a bug in core_tpg_check_initiator_node_acl() -> core_tpg_get_initiator_node_acl() where a dynamically created se_node_acl generated during session login would be skipped during subsequent lookup due to the '!acl->dynamic_node_acl' check, causing a new se_node_acl to be created with a duplicate ->initiatorname. This would occur when a fabric endpoint was configured with TFO->tpg_check_demo_mode()=1 + TPF->tpg_check_demo_mode_cache()=1 preventing the release of an existing se_node_acl during se_session shutdown. Also, drop the unnecessary usage of core_tpg_get_initiator_node_acl() within core_dev_init_initiator_node_lun_acl() that originally required the extra '!acl->dynamic_node_acl' check, and just pass the configfs provided se_node_acl pointer instead.

/* target_core_tmr.c */
target: Add TMR_ABORT_TASK task management support This patch adds initial support for TMR_ABORT_TASK ops for se_cmd descriptors using se_sess->sess_cmd_list and se_cmd->cmd_kref counting. It will perform an explict abort for all outstanding se_cmd ops based upon tmr->ref_task_tag that have not been set CMD_T_COMPLETE. It will cancel se_cmd->work and wait for backing I/O to complete before attempting to send SAM_STAT_TASK_ABORTED and perform target_put_sess_cmd() to release the referenced descriptor. It also adds a CMD_T_ABORTED check into transport_complete_task() to catch the completion from backend I/O that has been aborted, and updates transport_wait_for_tasks() to allow CMD_T_ABORTED usage with core_tmr_abort_task() context.

target: Add percpu refcounting for se_lun access This patch adds percpu refcounting for se_lun access that allows the association of an se_lun + se_cmd in transport_lookup_cmd_lun() to occur without an extra list_head for tracking outstanding I/O during se_lun shutdown. This effectively changes se_lun shutdown logic to wait for outstanding I/O percpu references to complete in transport_lun_remove_cmd() using se_lun->lun_ref_comp, instead of explicitly draining the per se_lun command list and waiting for individual se_cmd descriptor processing to complete.
