From aede25011fddf559dcf216d86975187e3f64b109 Mon Sep 17 00:00:00 2001 From: Erez Shitrit Date: Wed, 16 Oct 2013 17:37:50 +0300 Subject: [PATCH] IPoIB: Avoid flushing the driver workqueue on dev_down The driver should not flush the whole workqueue when only one work (the pkey poll one) needs to be cancelled. Use cancel_delayed_work_sync() instead.
