anon_inodes: mark the anon inode private
Eric Paris authored 
Inotify was switched to use anon_inode instead of its own private filesystem
which only had one inode in commit c44dcc56

 "switch inotify_user to
anon_inode"

The problem with this is that now the inotify inode is not a distinct inode
which can be managed by LSMs.  userspace tools which use inotify were allowed
to use the inotify inode but may not have had permission to do read/write type
operations on the anon_inode.  After looking at the anon_inode and its users
it looks like the best solution is to just mark the anon_inode as S_PRIVATE
so the security system will ignore it.
