3.15 and earlier lacks ktime_before in addition, see e.g. http://buildbot.kiszka.org/kvm-kmod/builders/3-next/builds/395/steps/3.15-x86-64/logs/stdio I'm not yet sure where to cut backward support now, maybe 3.10 (LTS). 3.9 gives a strange warning in __do_insn_fetch_bytes though the involved code should be identical to building for newer kernels: http://buildbot.kiszka.org/kvm-kmod/builders/3-next/builds/395/steps/3.9-x86-64/logs/stdio Jan -- Siemens AG, Corporate Technology, CT RTC ITP SES-DE Corporate Competence Center Embedded Linux -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
