Merge branch 'inet-sk_error-tracers'
Alexander Aring says:
====================
net: sock: add tracers for inet socket errors
this patch series introduce tracers for sk_error_report socket callback
calls. The use-case is that a user space application can monitor them
and making an own heuristic about bad peer connections even over a
socket lifetime. To make a specific example it could be use in the Linux
cluster world to fence a "bad" behaving node. For now it's okay to only
trace inet sockets. Other socket families can introduce their own tracers
easily.
Example output with trace-cmd:
<idle>-0 [003] 201.799437: inet_sk_error_report: family=AF_INET protocol=IPPROTO_TCP sport=21064 dport=38941 saddr=192.168.122.57 daddr=192.168.122.251 saddrv6=::ffff:192.168.122.57 daddrv6=::ffff:192.168.122.251 error=104

changes since v2:
- change "sk.sk_error_report(&ipc->sk);" to "sk_error_report(&ipc->sk);"
in net/qrtr/qrtr.c
