From 0f47ae0b3ec35dc5f4723f2e0ad0f6f3f55e9bcd Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Tue, 17 Jan 2006 09:53:51 -0800 Subject: [PATCH] IB/sa_query: Flush scheduled work before unloading module sa_query schedules work on IB asynchronous events. After unregistering the async event handler, make sure that this work has completed before releasing the IB device (and possibly allowing the sa_query module text to go away).
