Current set of exclusive operation states is not sufficient to handle all practical use cases. In particular there is a need to be able to add a device to a filesystem that have paused balance. Currently there is no way to distinguish between a running and a paused balance. Fix this by introducing BTRFS_EXCLOP_BALANCE_PAUSED which is going to be set in 2 occasions: 1. When a filesystem is mounted with skip_balance and there is an unfinished balance it will now be into BALANCE_PAUSED instead of simply BALANCE state. 2. When a running 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.
