Subject: [PATCH AUTOSEL 5.13 19/19] nilfs2: fix memory leak in nilfs_sysfs_delete_snapshot_group
Date: Mon, 13 Sep 2021 18:34:15 -0400	[thread overview]
Message-ID: <20210913223415.435654-19-sashal@kernel.org> (raw)
In-Reply-To: <20210913223415.435654-1-sashal@kernel.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".
