Previously, bch2_bkey_sectors_need_rebalance() called bch2_target_accepts_data(), checking whether the target is writable. However, this means that adding or removing devices from a target would change the value of bch2_bkey_sectors_need_rebalance() for an existing extent; this needs to be invariant so that the extent trigger can correctly maintain rebalance_work accounting. Instead, check target_accepts_data() in io_opts_to_rebalance_opts(), before creating the bch_extent_rebalance entry. This fixes (one?) cause of rebalance_work accounting being off.

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 reStructuredText 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.
