Subject: [PATCH v9-resend 04/54] dyndbg: make ddebug_class_param union members same size
Date: Tue, 16 Jul 2024 12:57:16 -0600 [thread overview]
Message-ID: <20240716185806.1572048-5-jim.cromie@gmail.com> (raw)
In-Reply-To: <20240716185806.1572048-1-jim.cromie@gmail.com>
struct ddebug_class_param keeps a ref to the state-storage of the
param; make both class-types use the same unsigned long storage type.
ISTM this is simpler and safer; it avoids an irrelevant difference,
and if 2 users somehow get class-type mixed up (or refer to the wrong
union member), at least they will both see the same value.
