Subject: [PATCH v3 0/2] [net] af_unix: return data from multiple SKBs on recv() with MSG_PEEK flag

This patch set implements a bugfix for kernel.org bugzilla #12323, allowing
MSG_PEEK to return all queued data on the unix domain socket, not just the
data contained in a single SKB. 

This is the v3 version of this patch, which includes a suggested modification
by Eric Dumazet to convert the unix_sk() conversion macro to a static inline
function. These patches are independent and can be applied separately.

This set was tested over a 24-hour period, utilizing a loop continually 
executing the bugzilla issue attached python code. It was instrumented with
a pr_err_once() ([   13.798683] unix: went there at least one time).

  [net] af_unix: Convert the unix_sk macro to an inline function for    
    type safety
  [net] af_unix: return data from multiple SKBs on recv() with MSG_PEEK
    flag
