Please consider fixing the output macros to allow formats, as the pr_* macros do. Also, why do you need "if (verbose)" if the name of the macro has VERBOSE_ in it; shouldn't that mean it checks verbosity itself? (Another good reason not to create a unique verbosity level mechanism, and to use the kernel mechanisms instead.) > while (!kthread_should_stop()) { > torture_shutdown_absorb(title); > schedule_timeout_uninterruptible(1); > -- > 1.8.1.5 > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
