Hello!

For reference there is a *slightly* more recent forward port of those
patches in the main SELinux repo under the working-selinuxns branch.
I haven't forward ported those patches since v5.10-rc1 as there are
some rather significant technical hurdles around persistent object
labeling which I don't believe have been adequately resolved yet.  The
prefixed/namespaces xattr approach that you mention above may work for
a limited number of namespaces, but I worry there is a scalability
issue that needs to be resolved; we can't simply keep adding xattrs to
inodes.

Also, are there rest of your patches online anywhere?  Patch 1/1 isn't
very interesting on its own.
