Subject: [PATCH net-next 0/2] net: cleanup datagram receive helpers
Date: Thu, 27 Feb 2020 12:30:36 +0100 [thread overview]
Message-ID: <cover.1582802470.git.pabeni@redhat.com> (raw)
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
Paolo Abeni (2):
unix: uses an atomic type for scm files accounting
net: datagram: drop 'destructor' argument from several helpers
