[PATCH V2 0/1] mm/slub: release kobject if kobject_init_and_add failed in sysfs_slab_add

[Xin Hao]

In kobject_init_and_add() function, the refcount is setted by calling
kobject_init() function, regardless of whether the return value is zero
or not, therefore, we must call kobject_del(&s->kobj) to prevent memory
of s->kobj is leaked.

V1 -> V2
use kobject_put() instead kobject_del().
