Subject: [PATCH 2/2] kasan, mm: reset tag for hex dump address
Date: Tue, 27 Jul 2021 12:00:21 +0800	[thread overview]
Message-ID: <20210727040021.21371-3-Kuan-Ying.Lee@mediatek.com> (raw)
In-Reply-To: <20210727040021.21371-1-Kuan-Ying.Lee@mediatek.com>

Text is a string. We need to move this kasan_reset_tag()
to address but text.
