Hello,

I understand your frustration with the existing LSM hooks/API and your 
reasoning for abandoning LSM in favor of a new set of hooks, however, I 
think this sets a dangerous precedence which could result in an 
abundance of security related hooks scattered throughout the kernel.  I 
would much rather see the LSM API extended/tweaked to support the needs 
of SAKURA and TOMOYO than ignored and duplicated; I suspect several 
others will say the same.

You have made good progress with TOMOYO so far and if I can remember 
correctly you really only have one hurdle left, the VFS portion.  
Please continue to seek a solution to this that fits within the LSM 
framework.

Thank you.
