Hello Vivek, Another patch that we would like to have upstream is the vmcoreinfo note intitialization. This is independent from the s390 kdump port. We need that for our traditional stand-alone and hypervisor dump tools. You already have agreed that the patch looks ok: https://lkml.org/lkml/2011/7/20/296 So could we get an ACK from you for the patch? [1] kdump: Initialize vmcoreinfo note at startup [2] s390: Export vmcoreinfo note Thanks! Michael
