Subject: [PATCH v4 1/4] trailers: export action enums and corresponding lookup functions
Date: Tue, 1 Aug 2017 11:03:30 +0200 [thread overview]
Message-ID: <20170801090333.32642-2-bonzini@gnu.org> (raw)
In-Reply-To: <20170801090333.32642-1-bonzini@gnu.org>
From: Paolo Bonzini <pbonzini@redhat.com>
Separate the mechanical changes out of the next patch. The functions
are changed to take a pointer to enum, because struct conf_info is not
going to be public.
Set the default values explicitly in default_conf_info, since they are
not anymore close to default_conf_info and it's not obvious which
constant has value 0. With the next patches, in fact, the values will
not be zero anymore!
