Instead of taking the buffer and length, update_and_write_aptpl() will allocate the buffer as needed, and then free it. Instead, the function takes an 'aptpl' boolean parameter. This enables us to remove memory alloc/frees from struct t10_pr_registration and other spots. There is a slight loss of functionality because each callsite doesn't get its own pr_debug any more, but this info can be cleaned via ftrace if necessary and I think the shorter code is worth it.
