[ Upstream commit 7d7672bc5d1038c745716c397d892d21e29de71c ] If count_max_extents() uses BTRFS_MAX_EXTENT_SIZE to calculate the number of extents needed, btrfs release the metadata reservation too much on its way to write out the data. Now that BTRFS_MAX_EXTENT_SIZE is replaced with fs_info->max_extent_size, convert count_max_extents() to use it instead, and fix the calculation of the metadata reservation.

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.
