For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ >From 3c8fad6c47a704c326065d2b312d495f013b8dd6 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Fri, 23 Nov 2012 12:07:39 +0800 Subject: [PATCH] iscsit: use GFP_ATOMIC under spin lock commit 3c989d7603872bf878840f7ce3ea49b73bea4c6c upstream. The function iscsit_build_conn_drop_async_message() is called from iscsit_close_connection() with spin lock 'sess->conn_lock' held, so we should use GFP_ATOMIC instead of GFP_KERNEL.
