Subject: [PATCH net-next v2 0/2] net: cleanup datagram receive helpers

Several receive helpers have an optional destructor argument, which uglify
the code a bit and is taxed by retpoline overhead.

This series refactor the code so that we can drop such optional argument,
cleaning the helpers a bit and avoiding an indirect call in fast path.

The first patch refactor a bit the caller, so that the second patch
actually dropping the argument is more straight-forward

v1 -> v2:
 - call scm_stat_del() only when not peeking - Kirill
 - fix build issue with CONFIG_INET_ESPINTCP

Paolo Abeni (2):
  unix: uses an atomic type for scm files accounting
  net: datagram: drop 'destructor' argument from several helpers
