Currently paused balance precludes adding a device since they are both considered exclusive ops and we can have at most one running at a time. This is problematic in case a filesystem encounters an ENOSPC situation while balance is running, in this case the only thing the user can do is mount the fs with "skip_balance" which pauses balance and delete some data to free up space for balance. However, it should be possible to add a new device when balance is paused. Fix this by allowing device add to proceed when balance is paused.

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.
