[Crash-utility] Re: s390dbf support for crash

Hi Dave, For lcrash we have a command, to print out kernel traces from the s390 debug feature (s390dbf). The debug feature is an s390 kernel trace API which uses wraparound buffers to store trace records in memory. Many of the s390 device drivers use this feature. Since more and more service and support people use crash instead of lcrash for dump analysis, it would be very useful to have this command in the crash dumpanalysis tool, too. There is some documentation of the s390dbf in the kernel sources under /Documentation/s390/s390dbf.txt
