Subject[PATCH 5.10 360/563] net: bonding: debug: avoid printing debug logs when bond is not notifying peers
Date
From: Suresh Kumar <surkumar@redhat.com>

[ Upstream commit fee32de284ac277ba434a2d59f8ce46528ff3946 ]

Currently "bond_should_notify_peers: slave ..." messages are printed whenever
"bond_should_notify_peers" function is called.

This is confusing and can also clutter up debug logs.
Print logs only when the peer notification happens.
