This appears\nto have been done because its use is within functions that take the\nport_info as a primary argument.\n\nHowever, this complicates managing the lifecycle of the field. The\nport_info structure is allocated in ice_init_hw() using devm, and it is\nnot released until the devm cleanup when the driver is unloaded.\n\nThe ice_init_hw() function is called in many places, including devlink\nreload, and possibly during DDP load after updating the Tx scheduler\nlayout.\n\nAdding a call of xa_destroy to the ice_deinit_hw() causes Sashiko to raise\nmultiple concerns due to potential ordering issues and possible ways that\nport_info could be a dangling reference.\n\nTo handle this, move the sched_node_ids out of port_info and into the hw\nstructure. All users of the array already have a pointer to hw anyways, and\nthere is only one sched_node_ids per adapter. While here, remove the overly\nverbose comment explaining the nature of the sched_node_ids xarray.\n\nAdd the missing xa_destroy to the cleanup path and to ice_deinit_hw(),\nensuring that we properly release the xarray memory.\n\nThis was caught by Sashiko during development of unrelated code."
