From 1a908c735aed44c8bbed303371202e416813b271 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Sat, 26 Jan 2008 14:10:50 +0100 Subject: [PATCH] [S390] cio: Fix ungroup vs. machine check race in ccwgroup. There are two ways for a ccwgroup device to be unregistered: Via the ungroup attribute, or when on of the slave devices is killed by a machine check. As we have to unregister the ccwgroup device via a callback, we'll now have to check whether it hasn't been already unregistered because of a machine check.
