[PATCH AUTOSEL 5.16 127/217] net: bonding: debug: avoid printing debug logs when bond is not notifying peers

From: Sasha Levin <sashal@kernel.org>
Date: 2022-01-18 02:33:26
Also in: lkml, stable
Subsystem: bonding driver, networking drivers, the rest · Maintainers: Jay Vosburgh, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Suresh Kumar <redacted>

[ 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.
