When evicting an inode, we are incorrectly calculating the amount of space required for a single delayed reference in case the free space tree is enabled. We have to multiply by 2 the result of btrfs_calc_insert_metadata_size(). We should be calculating according to the size update and space release of the delayed block reserve logic at btrfs_update_delayed_refs_rsv() and btrfs_delayed_refs_rsv_release(). Fix this by using the btrfs_calc_delayed_ref_bytes() helper at evict_refill_and_join() instead of btrfs_calc_insert_metadata_size().

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.
