Awhile back the meaning of is_available_bucket() and thus also bch_dev_usage->buckets_unavailable changed to include buckets that are owned by the allocator - this was so that the stat could be persisted like other allocation information, and wouldn't have to be regenerated by walking each bucket at mount time. This broke copygc, which needs to consider buckets that are reclaimable and haven't yet been grabbed by the allocator thread and moved onta freelist. This patch fixes that by adding dev_buckets_reclaimable() for copygc and the allocator thread, and cleans up some of the callers a bit.

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.
