Date: Wed, 9 Aug 2006 11:10:01 +0200 From: Martin Schwidefsky <schwidefsky@...ibm.com> To: linux-kernel@...r.kernel.org, horst.hummel@...ibm.com Subject: [patch] s390: dasd set offline kernel bug. From: Horst Hummel <horst.hummel@...ibm.com> [S390] dasd set offline kernel bug. The request queue flush function of the dasd driver has to dequeue the requests first and then call the end request function. Otherwise a kernel bug in ll_rw_block.c might get triggered.
