From 1ad62a19f177e61d4dde111ba35fb4badd0c2106 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 24 Aug 2005 14:41:51 -0700 Subject: [PATCH] IPoIB: Fix device removal race Currently we may have work scheduled in default kernel workqueue when the device is going down. The device could get freed before this workqueue gets serviced. I am actually seeing this causing system hangs. The following patch fixes this by using ipoib_workqueue which gets flushed when the device is going down. Signed-off-by: Michael S.
