Subject: [PATCH net-next V1 3/3] net/bnx2x: Use is_kdump_kernel() to detect kdump kernel
Date: Mon, 25 Aug 2014 16:06:54 +0300	[thread overview]
Message-ID: <1408972014-13319-4-git-send-email-amirv@mellanox.com> (raw)
In-Reply-To: <1408972014-13319-1-git-send-email-amirv@mellanox.com>

Use is_kdump_kernel() to detect kdump kernel, instead of
reset_devices.
