Subject: [PATCH 4.1 08/29] net: eth: altera: fix napi poll_list corruption
Date: Thu,  1 Oct 2015 11:31:44 +0200	[thread overview]
Message-ID: <20151001093146.073807514@linuxfoundation.org> (raw)
In-Reply-To: <20151001093145.730759857@linuxfoundation.org>

4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Atsushi Nemoto <nemoto@toshiba-tops.co.jp>

[ Upstream commit 4548a697e4969d695047cebd6d9af5e2f6cc728e ]

tse_poll() calls __napi_complete() with irq enabled.  This leads napi
poll_list corruption and may stop all napi drivers working.
Use napi_complete() instead of __napi_complete().
