Subject[PATCH 052/222] iscsit: use GFP_ATOMIC under spin lock
Date
3.5.7.3 -stable review patch.  If anyone has any objections, please let me know.

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

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

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.
