From a4b7cfaee487caef913be978dce60896fe741268 Mon Sep 17 00:00:00 2001 From: Chris Leech Date: Tue, 25 Aug 2009 13:59:08 -0700 Subject: [PATCH] [SCSI] libfcoe: fcoe_ctlr_destroy use cancel_work_sync instead of flush_work Use cancel_work_sync() in place of flush_work(), so that fcoe_ctlr_destroy() can be called from a workqueue. Also, purge the receive queue after the recv_work has been cancled because if recv_work isn't run it's not guaranteed to be empty now.
