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,
