Message-Id: <1408972014-13319-2-git-send-email-amirv@mellanox.com> Date: Mon, 25 Aug 2014 16:06:52 +0300 From: Amir Vadai <amirv@...lanox.com> To: "David S. Miller" <davem@...emloft.net>, Andi Kleen <andi@...stfloor.org> Cc: netdev@...r.kernel.org, Andrew Morton <akpm@...ux-foundation.org>, Vivek Goyal <vgoyal@...hat.com>, Or Gerlitz <ogerlitz@...lanox.com>, Yevgeny Petrilin <yevgenyp@...lanox.com>, Amir Vadai <amirv@...lanox.com> Subject: [PATCH net-next V1 1/3] crash_dump: Make is_kdump_kernel() accessible from modules In order to make is_kdump_kernel() accessible from modules, need to make elfcorehdr_addr exported. This was rejected in the past [1] because reset_devices was prefered in that context (reseting the device in kdump kernel), but now there are some network drivers that need to reduce memory usage when loaded from a kdump kernel. And in that context, is_kdump_kernel() suits better.
