Subject: [PATCH V2 0/1] mm/slub: release kobject if kobject_init_and_add failed in sysfs_slab_add
Date: Thu, 11 Aug 2022 15:18:43 +0800 [thread overview]
Message-ID: <20220811071844.74020-1-xhao@linux.alibaba.com> (raw)
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().
V1:
