This patch allows to have a different binfmt_misc configuration
for each new user namespace. By default, the binfmt_misc configuration
is the one of the previous level, but if the binfmt_misc filesystem is
mounted in the new namespace a new empty binfmt instance is created and
used in this namespace.

For instance, using "unshare" we can start a chroot of another
architecture and configure the binfmt_misc interpreter without being root
to run the binaries in this chroot.

Thanks,

I don't konw who is the maintainer for this part, but is there any
chance to have this merged in 4.20?

Thanks,
Laurent
