From c5205f2ff2bec6acf398211aed66b3e6ac44eee6 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Mon, 4 Jun 2018 19:07:39 +0200 Subject: s390/dasd: move dasd_ccw_req to per request data Let the block layer allocate per request data to store struct dasd_ccw_req. We still need extra preallocated memory for usage by ccw programs (which vary in length) and for requests which don't originate from the block layer.
