Kconfig patch for raw driver on s390x
Updating PM score. I'm having troubles reserving an s390 system, unfortunately. However, it looks to me like raw devices are supported on s390 already. If you have access to an s390 system, please check to see if /dev/rawctl exists, and whether the raw command works for binding devices. Thanks! I managed to reserve a system and rawctl is not available. The attached patch applied with minimal offsets and worked as advertised. I was not able to verify that I/O could be performed to a raw device because of the configuration of the system I was using. Is there any chance we can get testing from the customer on this? Simply performing some dd commands should be sufficient. Thanks! in kernel-2.6.18-141.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 Please do NOT transition this bugzilla state to VERIFIED until our QE team has sent specific instructions indicating when to do so. However feel free to provide a comment indicating that this fix has been verified. ~~ Attention - RHEL 5.4 Beta Released! ~~ RHEL 5.4 Beta has been released!
