Subject: ubi: fastmap: use kmem_cache_free to deallocate memory
Date: Sun, 29 Oct 2017 20:40:02 +0800 [thread overview]
Message-ID: <1509280802-14620-1-git-send-email-bianpan2016@163.com> (raw)
Memory allocated by kmem_cache_alloc() should not be deallocated with
kfree(). Use kmem_cache_free() instead.
