[Ocfs2-devel] o2net: log socket state changes

[Sunil Mushran]

KERN_INFO is a good idea. But the message is a mouthful.

Currently it reads:
"node %s (num %u) at %u.%u.%u.%u:%u socket state changed to X. Shutting 
down the socket connection"

How about this:
"o2net: connection to node %s (num %u) at %u.%u.%u.%u:%u shutdown, state %d"

printk(KERN_INFO "connection to " SC_NODEF_FMT " shutdown, state %d" ....);
