Hi Mickael,
Sorry about the long silence on this work, As we known this work depends
on another work about changing argument from struct dentry to struct
path for some attr/xattr related lsm hooks, I'm stuck with this thing,
because IMA/EVM is a special security module which is not LSM-based
currently, and severely coupled with the file system. so I am waiting
for Roberto Sassu' work (Move IMA and EVM to the LSM infrastructure) to
be ready, I think it can make my work more easy. you can find
Roberto'work here,

Any good idea are welcome, thanks.
Thanks for the update Xiu.
Which part would be needed from Roberto's patch series?
