[PATCH 0/4] RFC: Improvements to flow specific logging

[David Gibson <david@gibson.dropbear.id.au>]

While working on podman bug 23739, I found some deficiences in how and
when we report various socket errors related to specific flows.  Here
are some preliminary patches to improve that.

I think patches 1..3 are pretty straightforward and safe.  4/4 I think
is a good idea in principle - promoting the priority of a number of
messages now that we have ratelimiting.  However, plumbing 'now' all
the places we need it resuls in a *lot* of churn, so we might want to
postpone or split it up.

Still, current drafted posted for consideration.

David Gibson (4):
  flow: Regularise flow specific logging helpers
  flow: Include flow details with higher priority log messages
  flow: Safer errno handling in flowside_connect() callers
  flow, treewide: Promote priority of selected flow-linked messages
