When starting a transaction, we are assuming the number of bytes used for each delayed ref update matches the number of bytes used for each item update, that is the return value of: btrfs_calc_insert_metadata_size(fs_info, num_items) However that is not correct when we are using the free space tree, as we need to multiply that value by 2, since delayed ref updates need to modify the free space tree besides the extent tree. So fix this by using btrfs_calc_delayed_ref_bytes() to get the correct number of bytes used for delayed ref updates.

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.
