CONFIG_CGROUPS is "not fixed"? I think Tejun would like to have some words with you :) Anyway, yes, it's an option, but given that people are using this metadata today in userspace just fine, I fail to see how having the kernel be a transport for this same data is an issue. When the kernel is the transport, it can do so in a race-free way, and you can properly do security tests/logic based on it. thanks, greg k-h -- 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/
