Subject: [PATCH v5 01/12] staticcall: move struct static_call_key definition to static_call_types.h
Date: Mon, 8 Mar 2021 13:28:33 +0100 [thread overview]
Message-ID: <20210308122844.30488-2-jgross@suse.com> (raw)
In-Reply-To: <20210308122844.30488-1-jgross@suse.com>
Having the definition of static_call() in static_call_types.h makes
no sense as long struct static_call_key isn't defined there, as the
generic implementation of static_call() is referencing this structure.
So move the definition of struct static_call_key to static_call_types.h.
