X-Git-Tag: firefly_0821_release~176^2~4647^2~15^2~19 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=d8d9608fdd19f85a524db0a41bc2def5c88cbdd0;p=firefly-linux-kernel-4.4.55.git perf kvm: Make perf kvm diff support --guestmount. In manpage of perf-kvm, --guestmount is supported by diff command, but it does not work well. This patch change the extend the checking in buildid-diff from guestkallsyms or guestmodules to perf_guest. Then this checking can cover the all cases perf kvm is used for.
