Subject: [PATCH 4.9 23/26] nilfs2: fix memory leak in nilfs_sysfs_delete_snapshot_group
Date: Fri, 24 Sep 2021 14:44:11 +0200 [thread overview]
Message-ID: <20210924124329.116193216@linuxfoundation.org> (raw)
In-Reply-To: <20210924124328.336953942@linuxfoundation.org>
From: Nanyong Sun <sunnanyong@huawei.com>
[ Upstream commit 17243e1c3072b8417a5ebfc53065d0a87af7ca77 ]
kobject_put() should be used to cleanup the memory associated with the
kobject instead of kobject_del(). See the section "Kobject removal" of
"Documentation/core-api/kobject.rst".
