https://docs.kernel.org/process/maintainer-netdev.html#using-device-managed-and-cleanup-h-constructs

  Low level cleanup constructs (such as __free()) can be used when
  building APIs and helpers, especially scoped iterators. However,
  direct use of __free() within networking core and drivers is
  discouraged. Similar guidance applies to declaring variables
  mid-function.
