    userns: Pass a userns parameter into posix_acl_to_xattr and posix_acl_from_xattr · 5f3a4a28
    Eric W. Biederman authored
     - Pass the user namespace the uid and gid values in the xattr are stored
       in into posix_acl_from_xattr.
    
     - Pass the user namespace kuid and kgid values should be converted into
       when storing uid and gid values in an xattr in posix_acl_to_xattr.
    
    - Modify all callers of posix_acl_from_xattr and posix_acl_to_xattr to
      pass in &init_user_ns.
    
    In the short term this change is not strictly needed but it makes the
    code clearer.  In the longer term this change is necessary to be able to
    mount filesystems outside of the initial user namespace that natively
    store posix acls in the linux xattr format.
