This looks like a useful thing but I wonder if a debugfs file would be more appropriate than sysctl.

I believe sysctl is for permanent ABIs, right? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
