That > should be the trigger for a really in-depth review of the change. No UAPI header is touched by this patch series. That is because there are two definitions of struct kexec_segment, one in include/linux/kexec.h and the other one in include/uapi/linux/kexec.h. My patch changed the former. I was unaware of the second definition in the latter. -- []'s Thiago Jung Bauermann IBM Linux Technology Center
