From: Bjorn Helgaas <bhelgaas@...gle.com>
To: "David S. Miller" <davem@...emloft.net>
Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH v2] net: Fix typos and whitespace.
Fix typos. Capitalize CPU, NAPI, RCU consistently. Align structure
indentation. No functional change intended; only comment and whitespace
changes.
