Subject[PATCH 4/6] nilfs2: fix memory leak in nilfs_sysfs_delete_##name##_group
Date
From: Nanyong Sun <sunnanyong@huawei.com>

The 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".
