Hi nab, hch, and all,
This patchset reduces the amount of memory for se_dev_entry and se_lun
arrays by waiting to allocate array members until they are
created. This patch saves up to 261KB per TPG, and up to 65KB per
ACL. It also fixes a number of locking bugs around these data
structures.
Andy Grover (9):
target: Add locking to some accesses to nacl.device_list
target: Don't unlock/relock tpg_lun_lock in loop in add_node_to_devs
target: Allocate se_dev_entrys in device list only when used
target: core_tpg_post_dellun can return void
target: Change core_dev_del_lun to take a se_lun instead of
unpacked_lun
target: Rename core_tpg_post_dellun to remove_lun
target: Allocate se_luns only when used
target: Remove core_tpg_release_virtual_lun0 function
target: Refactor core_enable_device_list_for_node
