[PATCH] set mnt_namespace in the correct place
This patch sets ->mnt_namespace where it's actually added to the namespace. Previously mnt_namespace was set in do_kern_mount() even if the filesystem was never added to any process's namespace (most kernel-internal filesystems). This discrepancy doesn't actually cause any problems, but it's cleaner if mnt_namespace is NULL for these non exported filesystems.
