Once again, I don't really care too much either way.  My only selfish
motivation is to make it as frictionless as possible to get the
SELinux tree merged into Linus' tree.

I don't really understand what advantage one repo with multiple
branches has over multiple repos, e.g. Linus' just pulling from the
individual LSM trees directly.  I suppose one could make an argument
about linux-next, but I know they prefer to pull from the individual
repos directly (they pull selinux/next directly).  Is it to help
reduce the load on Linus?

>From my perspective, the linux-security tree only introduces another
opportunity for things to go wrong during the merge window (as
evidenced by this latest snafu).  Help me understand why a single tree
with multiple branches is beneficial to multiple trees?

Also, to be clear, I'm not picking on IMA or Mimi; this could have
easily been SELinux screwing things up for IMA (or Smack, or AppArmor,
etc.).
