Subject: [PATCH] mm: mempool: Remove unused argument in kasan_unpoison_element() and remove_element()
Date:   Thu, 21 Jun 2018 15:03:32 +0800
Message-Id: <20180621070332.16633-1-baijiaju1990@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The argument "gfp_t flags" is not used in kasan_unpoison_element() 
and remove_element(), so remove it.
