Subject: [PATCH RFC v6 01/21] llist: Move llist_{head,node} definition to types.h
Date:   Wed,  4 May 2022 17:17:29 +0900
Message-Id: <1651652269-15342-2-git-send-email-byungchul.park@lge.com>
In-Reply-To: <1651652269-15342-1-git-send-email-byungchul.park@lge.com>
References: <1651652269-15342-1-git-send-email-byungchul.park@lge.com>
Precedence: bulk

llist_head and llist_node can be used by very primitives. For example,
Dept for tracking dependency uses llist things in its header. To avoid
header dependency, move those to types.h.
