[PATCH] aio: use kmem_cache_free() instead of kfree()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



memory allocated by kmem_cache_alloc() should be freed using
kmem_cache_free(), not kfree().

Fixes: fa0ca2aee3be ("deal with get_reqs_available() in aio_get_req() itself")
