[PATCH] uapi/linux/keyctl.h: don't use C++ reserved keyword as a struct member name

[PATCH] uapi/linux/keyctl.h: don't use C++ reserved keyword as a struct member name

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Since this header is in "include/uapi/linux/", apparently people
want to use it in userspace programs -- even in C++ ones.
However, the header uses a C++ reserved keyword ("private"),
so change that to "dh_private" instead to allow the header file
to be used in C++ userspace.

Ugh.  Yeah.  This is a UAPI breaker, but I think we have to do it, despite it
being 2 years old.  Maybe wrap that element in a #ifdef so it's still allowed
in C?

I agree with David's assessment.

The keyctl() system call wrapper is implemented in libkeyutils, which may 
reduce the need for the proposed ifdef. libkeyutils and its users don't 
require any updates if this patch is merged because it has its own 
keyword-free structure definition.
