Merge branch 'af_unix-introduce-so_inq-scm_inq'
Kuniyuki Iwashima says:
====================
af_unix: Introduce SO_INQ & SCM_INQ.
We have an application that uses almost the same code for TCP and
AF_UNIX (SOCK_STREAM).
The application uses TCP_INQ for TCP, but AF_UNIX doesn't have it
and requires an extra syscall, ioctl(SIOCINQ) or getsockopt(SO_MEMINFO)
as an alternative.
Also, ioctl(SIOCINQ) for AF_UNIX SOCK_STREAM is more expensive because
it needs to iterate all skb in the receive queue.
This series adds a cached field for SIOCINQ to speed it up and introduce
SO_INQ, the generic version of TCP_INQ to get the queue length as cmsg in
each recvmsg().
