I don't recall why "integrity" is on the security_initcall, while both
IMA and EVM are on the late_initcall().

It's because integrity needs to have a VFS buffer allocated extremely
early, so it used the security init to do it. While it's not an LSM,
it does use this part of LSM infrastructure. I didn't see an obvious
alternative at the time, but now that I think about it, maybe just a
simple postcore_initcall() would work?
