Will do. Something along the lines of "how long does it take to execute two gazillions of getppid()?" I'll send v2 shortly - I just figured out what was this mysterious dance with allocating "not-quite-full struct pt_regs" on interrupt path: It is intended to make nested interrupts to have better backtraces. I broke that by this patch, v2 will have this feature retained. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
