Subject: [PATCH 6/6] nilfs2: fix memory leak in nilfs_sysfs_delete_snapshot_group
From: Nanyong Sun <sunnanyong@...wei.com>
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".
