Hi all,
Here is -v2 series for converting LIO target se_node_acl + se_lun
mapping tables from fixed size arrays to dynamic RCU hlist_heads.
This turns fast-path I/O into a lock-less RCU reader using existing
percpu based se_lun->lun_ref logic, and converts the RCU updat

This patch converts the core_scsi3_pr_seq_non_holder() check for non
reservation holding registrations to use an atomic bitop.
It also includes associated set_bit() in __core_scsi3_add_registration()
and clear_bit() __core_scsi3_free_registration() for the updater path.

This patch converts the fixed size se_portal_group->tpg_lun_list[]

number of se_lun ports per target endpoint.

This patch converts core_tpg_deregister() to perform a list splice

This patch changes __core_scsi3_do_alloc_registration() code to
drop pr_reg->pr_reg_tg_pt_lun pointer usage in favor of a new
pr_reg RPTI + existing target_lun.
It also includes changes to REGISTER, REGISTER_AND_MOVE and APTPL
feature bit codepaths.

This patch converts se_tpg->acl_node_lock to struct mutex, so that
->acl_node_acl walkers in core_clear_lun_from_tpg() can block when

It also updates core_dev_add_lun() to hold ->acl_node_mutex when

This patch changes core_tpg_add_node_to_devs() to avoid unnecessarly
resetting every se_dev_entry in se_node_acl->tpg_lun_hlist when the
operation is driven by an explicit configfs se_lun->lun_group creation
via core_dev_add_lun() to only update a single se_lun.
