The commit "s390/dasd: add query host access to volume support" introduces is an attribute 'host_access_count' to find out how many systems are using a particular device. This is indeed a new feature. The other large dasd patch "s390/dasd: reorder lcu and device lock" is a far better solution for the LCU locking that the git commit 9bfefde718c1352d "s390/dasd: fix incorrect locking order for LCU device add/remove" tries to solve. That commit has been added with the merge window patches for 4.6. I really would like to see the "s390/dasd: reorder lcu and device lock" go into 4.6 as the current solution is really ugly. But I'll remove the patch with the new attribute. Would that be acceptable? -- blue skies, Martin.
