Maybe we should have a "unsafe for export" flag for events, if they do strange things like that? As it stands, I can't use trace-cmd on an x86 machine that has kvm enabled because it will try to read all the kvm stuff. Arguably, it should only try to parse it when it needs it (i.e. not for me) but still it's very inconvenient to export something to userspace that it cannot possibly understand. johannes --=-tbLn8ffqNyzL03QrjVRl Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJLCmyhAAoJEODzc/N7+QmaYZsP/j9LORSwWM+8MlKbmz9fdiTB AcV7FwodAlX7ffY3ZyzvDOjRfFsQq28bFy8/9eDG4YcZTQt075Fo9ZOj5fN9gnJe C+7/AbH8vVzxMW2mh4JgMfSviBlaOl+vycOyS4Xqa2x/k8Cosl00Omti+XrVh3+P FZzEeXYBtT2GMZFigkpwm4DNGhjqyH4iVW9ZbKTpV6chC3rw57eP78z6V9oYP8nj kiVghulrhsZfdG3NW+0WmxdiFNOKi3RNRIwKjYtYhe5ymY6a6fzF+85IszUrB1gb lwLYDOzjueb/lJ7g1Whvbkz6kSccFMCeONVnxzP/xrCFzZfbwnB44YeS83UeMt80 PHnXBYX96aaKxo8w+ppDml1cVDguDkrDYNnfh+K3nDTzFYFcrnoIO8io4rrJ/wKe hKGxi+zEqmdEIEH/h5zJ1DFUKwRaM/yRtVGYAUkb6fNOKwlyuK2Gy1Gujp2Bc96I dbuOaSC/z3rjyeXotnt+0tKKja/SUCMVTMz9PFEdbY9kymPS4jGHCVKqdgACN9jn CBbCcIJYmANldxWSMg5UVVs84OOTCPeWs3qCc+hAQj7EKQZzH0EjEo6OKZLwOMca VKCHy5EZ4omCHsGXCscmHgGGoECpXkOheepZL3b7epT2H38uUBvMUjeoUZanrXPL UX95Sv9iDkGO/2Ewl+l6 =qzkY -----END PGP SIGNATURE----- --=-tbLn8ffqNyzL03QrjVRl--
