Subject: mm/vmalloc: move free_vm_area(area) from the __vmalloc_area_node function to the __vmalloc_node_range_noprof function
Date: Mon, 3 Mar 2025 09:57:02 +0800
Moved free_vm_area from the __vmalloc_area_node function to the
__vmalloc_node_range_noprof function so that allocation and freeing of the
area can be paired in one function for better readability.
