From: David Howells <dhowells@...hat.com>
To: linux-kernel@...r.kernel.org
Subject: [PATCH 26/45] C++: Can't have variable/member names the same as
typedef names
Type names in C++ share a namespace with variable names and member names,
so struct member names can't have the same name as their type. Suffix
types with _t.
