Subject: [PATCH v3 07/16] zsmalloc: remove page_mapcount_reset
Date: Wed, 30 Mar 2016 16:12:06 +0900	[thread overview]
Message-ID: <1459321935-3655-8-git-send-email-minchan__29886.7161538967$1459321905$gmane$org@kernel.org> (raw)
In-Reply-To: <1459321935-3655-1-git-send-email-minchan@kernel.org>

We don't use page->_mapcount any more so no need to reset.
