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

From: Randy Dunlap
Date: Fri Apr 06 2018 - 14:58:31 EST


From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

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.

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=191051
