Revision cc2205a67dec5a700227a693fc113441e73e4641 authored by Miaohe Lin on 24 February 2021, 20:06:50 UTC, committed by Linus Torvalds on 24 February 2021, 21:38:32 UTC
In hugetlb_sysfs_add_hstate(), we would do kobject_put() on hstate_kobjs when failed to create sysfs group but forget to set hstate_kobjs to NULL. Then in hugetlb_register_node() error path, we may free it again via hugetlb_unregister_node().
