Hey, This is a tiny series to fully decouple idmapped mounts from namespaces. We already have a dedicated type and nothing matters from a namespace apart from it's permissions. So just get rid of it. Also means we could extend this to allow changing of idmapping completely independent of namespaces in the future. There's no need to tie them that close together. Survives xfstests for btrfs, ext4, xfs and specifically the idmapped mount tests. Thanks!
