- Change idx variable in DO_TRACE macro to __idx to avoid name conflicts. A kvm event had "idx" as a parameter and it confused the macro. - Fix a race where interrupts would be traced when set_graph_function was set. The previous patch set increased a race window that tricked the function graph tracer to think it should trace interrupts when it really should not have. The bug has been there before, but was seldom hit. Only the last patch series made it more common. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCXACrFhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qgUuAP9zZ0+PjDIXrkZATogEsMJ1OZKy5AiK mwT7S85/ouOeCQEAi5JUcSfwB0caq2nYB1GKOKNfDH0ffeVR4wNykcYjngM= =gjwC -----END PGP SIGNATURE----- Merge tag 'trace-v4.20-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull more tracing fixes from Steven Rostedt: "Two more fixes: - Change idx variable in DO_TRACE macro to __idx to avoid name conflicts.
