Subject: [Ocfs2-devel] [PATCH v3 01/10] kobject: introduce kobject_del_and_put()
Date: Thu, 23 Mar 2023 00:58:30 +0800 [thread overview]
Message-ID: <20230322165830.55071-1-frank.li@vivo.com> (raw)
There are plenty of using kobject_del() and kobject_put() together
in the kernel tree. This patch wraps these two calls in a single helper.
Signed-off-by: Yangtao Li <frank.li@vivo.com>
---
v3:
-convert to inline helper
v2:
-add kobject_del_and_put() users
