It is possible that a platform that is capable of 'namespace labels' comes up without the labels properly initialized. In this case, the region's 'align' attribute is hidden. Howerver, once the user does initialize he labels, the 'align' attribute still stays hidden, which is unexpected. The sysfs_update_group() API is meant to address this, and could be called during region probe, but it has entanglements with the device 'lockdep_mutex'. Therefore, simply make the 'align' attribute always visible. It doesn't matter what it says for label-less namespaces, since it is not possible to change their allocation anyway.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
