Subject: dm vdo: update min_heap_callbacks to use default builtin swap
Date: Sun, 20 Oct 2024 12:01:56 +0800
Replace the swp function pointer in the min_heap_callbacks of dm-vdo with
NULL, allowing direct usage of the default builtin swap implementation.
This modification simplifies the code and improves performance by removing
unnecessary function indirection.
