    VFS: Make clone_mnt()/copy_tree()/collect_mounts() return errors · be34d1a3
    David Howells authored
    copy_tree() can theoretically fail in a case other than ENOMEM, but always
    returns NULL which is interpreted by callers as -ENOMEM.  Change it to return
    an explicit error.
    Also change clone_mnt() for consistency and because union mounts will add new
    error cases.
    Thanks to Andreas Gruenbacher <agruen@suse.de> for a bug fix.
